This post is inspired by the recent closed thread about the TSC sharpener that turned ugly, and I tried to post this on there but by the time I got it written the thread had closed. :duh:

FWIW, here's what I do. I use a hand file, without a file guide, and push AND rotate the file at the same time through each and every stroke, starting at the master link of the chain. One determines where the master link is by finding two teeth in sequence that are on the same side of the bar. Then I stand over the saw with the bar held in a bench vice, (with magnetic plastic jaws to keep the bar from any damage). I use an adjustable light to shine onto the teeth so I can see what I'm doing and get a better view of the bar/chain. I lock the chain brake to keep the chain from moving, and use two hands on the file to balance it in the tooth and to not rock the file as I push out from the center to the outer edge of the bar through the tooth. Each tooth gets visually inspected in case it is damaged more then others. Once I've done all teeth and arrive back at the master link I flip the saw 180* in the vice and follow the same procedure on the other side. Then I use the *guide which rest on the top of the teeth and file the rakers as needed to keep them even with the overall tooth wear.
Stihl sells raker guides and a file kit that provide the proper tools to make hand sharpening effective and less frustrating, especially for those who are just beginning to sharpen their own chain.
* The guide I was talking about can be combined with a bar groove cleaner tool and the combination of the two, and a wood or plastic file handle for the rat tail end of the file are all what I consider necessities for any hand filer. Flipping the bar over with every chain sharpening or change to a sharp chain is also highly recommended. Ideally, one would have two bars and two chains for each saw and would change out the saw sprocket once the chains and bars are worn down. Tightening of the chain in the bar should be enough so there is just a slight amount of slack on the underside of the bar near where it enters the shoot when returning to the sprocket. Too tight and the saw can be damaged, too loose and the chain can/will come off the bar. Technically, when one shuts the saw down at the end of the day, one should loosen the chain slightly to not allow the chain to tighten when it cools and put stress on the saw bearings.
The Stihl and other brand saw sharpening kits are here: Amazon.com: stihl chainsaw sharpening kit

Note that each saw kit fits a specific saw chain size. The metal tool between the flat file and the round file is the guide I was referring to to properly adjust the rakers, clean the bar groove, etc.

Remember to spin the file in either the metal holder included in the file kit, or by hand if doing the sharpening by feel as I do most of the time. Replace the file when it no longer cuts metal off the teeth with little effort.

And, if you look carefully at where the laser lines are on the teeth one can get used to using them to guide where the file needs to go when sharpening. One other tip, try lining up the correct size file in a brand new chain on the bar in the vise to get a sense of what a sharp tooth angle looks like.
Personally, I don't mind taking the necessary amount of time to sharpen a chain, and if it takes more time than by machine so be it; I'm going to get more miles out of my chain, and I'm not doing production work or sharpening for anyone but me and my Stihls. I've considered buying a grinder, but unless I could get it for what the OP is buying his for, or less in case his first offer buyer doesn't close the deal, I don't need another piece of equipment in my shop.
Sharp saw chains are like a sharp knife, safer for the user and for the equipment.

And for those guys 'rocking' their saws on a regular basis maybe you should be paying closer attention to what and where you cut. I'm not saying I don't hit stuff like hidden barbed wire right after sharpening a chain, in fact that's the best way to locate metal or rocks, is to finish sharpening your chain in the field..... But some things are avoidable by experience- edges of fields, wire abounds, stumps, wetlands; rocks and dirt are everywhere.

One last thought. I do carry a file kit and a vise mounted to my rear rack on my ATV, and usually take both my tractor and ATV to wherever I'm going to cut on my property so to have a safe escape vehicle in case of unforeseen injury, since I usually work alone. I ALWAYS have my phone fully charged, sometimes a walkie-talkie, and chainsaw boots, chainsaw gloves, chaps, and full gear helmet with visor and earmuffs.
I hope this has been helpful to the OP and whomever else who reads this.
Feel free to PM me if further questions or thoughts arise.

Hi Coyote...

I have been using a filing guide for years. For me they do the best. Oregon makes these filing guides, too.

Here's a video that shows how I do it. Once you get the hang of it, you can do a chain pretty quick. I have one guide for each file size so I don't have to change out files for different chain sizes on my saws.

Thanks guys! I put a lot of thought into this thread's first post, with the hope that it might bolster the turned to c%ap thread that was recently closed, and now I see, reopened!? :confused2::eek: Wow, I just don't get what's going on with the posters and threads on the TBN forums!? It drives me NUTZ, just trying to get some useful info out there and threads turn to trash in no time.:confused3::rolleyes:

When I sharpen by hand, I just use a file and hand guide like this video shows. It works very well and is quick.

However, sometimes I am in a hurry, so I just change the chains out instead of field sharpening it. When I get home, I sharpen all of my chains on an electric sharpener, which is much faster.

Good information. Now a question. If you hit a rock with a chain it is said that you "rocked" the chain. So if you hit a piece of steel does it mean you "stealed" the chain? Just thought I might throw a little humor in here after the bickering that was on the other mentioned thread.

I sometime touch up a chain by hand however. We keep our chains accurate , true and factory sharp with a mechanical jig and grinding wheel. It is not humanly possible to maintain cutting efficiency and performance.

2x from my experience. A gig/fixture set up will give a more correctly sharped chain most of the time than free handing over a long period of time.

If I 'rock' or 'steel' one tooth I do not grind the others to match in most cases but let it rest until the other teeth wear to match as long as it cuts OK and straight.

No problem. You're welcome. Hope it's helpful.

No. It means you stole the chain, now give it back.

What's not humanly possible; accurate hand filing a chain? If so, I beg to differ. At it since 12 years old, now 61. It can be done, like anything else, with practice and patience. I'm not talking speed, but I am talking accuracy. To each his own, but don't try and tell me a grinder is a replacement for work that can be done by hand by someone with skill.

Great post Coyote & indicative of your many years of experience - nothing beats a hand filed chain !!:thumbsup:

The fact is either way works good if your good at it, I use a grinder but I'll give a slight edge in hand filing in cutting a hair faster. I,ve had more than one hand filers ask how I get a chain to cut that good with a grinder. Both way are bad if you not good at it. Steve

Hey Moss...That's a pretty good video. I learned several things! Such as measuring the teeth length with a small adjustable wrench and rounding the edges of the rakers with the file the way he did. I realize I don't know it all...

Hand filing is easy cheap and needs to be learned.

I run 6 saws from a Stihl 021 (35CC/2HP) to the big daddy - a Stihl 088 (122CC/8.5HP) and have about 30 or so chains.

I definitely do not agree with the video of "sharpen every tank". I mill trees. They dull chain. About 10' of hardwood and I have to touch up. From my 2010 post.
Seems like a lot of discussion on hand filing. Knowing how to hand file should be mandatory for anyone running a chain saw. But being able to keep all the angles proper and the rakers at the right depth is a difficult feat to master.
As I think I've posted elsewhere here I'm into chain saw milling.

I generally need to either swap or "touch up" chains about every 10' to 15' of 20" hardwood to keep every thing running smoothly. So my process is to hand file while outside, usually with a file and a Carlton File-O-Plate (FOP). That's the $5 solution.

Then when I get them inside (generally after having been "touched up" three times) I use a Granberg File'n Joint (a fancy file guide/jig) which is the $30 solution. This is probably good enough for most firewood cutters, especially if they don't rock the chain.

Then after 3 or so "Granberg" sharpenings (which would include about 9 or 10 FOP filings) I put it on the NT grinder to "true" all the angles up. That's the $100 solution.

One of the problems if you get your angles off is that the cut starts to curve a little, not much of a problem on a 2' crosscut, but a major problem on a 10' rip. Another is if you hit a nail or a rock and damage a few teeth, it's easier to grind them to get back in shape.

So I say learn to do it by hand, but also get a grinder if you do it a lot.

And watch your output. Sawdust is bad, nice big chips are good.

Some have better art skills than others for sure. Having a file for touch up is great. Dad when his entire life doing a lot of sawing only using a file after a shop 'ground' away a good chain on his first saw. Many will not master the file however so $50 more or less for a machine can be a good or bad solution depending on skills. As noted we are talking a 'kiss' of the wheel to a tooth. If you are making the fire fly on the first time to sharpen a new chain with a grinder you should have practiced more on an old chain. :)

I use a grinder now mostly ,in fact I like them so we'll I just ordered a maxx Italian job to replace my worn harbor freight one
As some of you might remember I do it as a sideline to my normal 60 hour a week job(nut ain't I) my boss hires me at home sharpen the chains from a machine we have with a 7 ft bar now that's a lot of filing by hand
I hemmed and hawed for a few years now to upgrade from the harbor freight cheapie but that has put a lot of cash in my pocket since I started my sideline I'm no stranger to grinding cutting tools I've done it as part of my lumber mill career for 30 years you can get good results with a cheap grinder if you have good technique
I've been following these threads and watching them go sour for several years on Tbn I until a few years ago I always hand filed and considered my self very good at it I usually cut 8 to 10 cord of wood a year for my family and relatives
Which is better ? Give me a grinder for rocked tooth if I could a file for touch up WHY ? I'm getting older I've had 2 carpitunel surgerys got arthritis in my hands and i pay for it when I hand file
Mabey I'm the first to admit but the bodys to worn out to hand file a lot

What we need is a file or grinder that tunes up old bodies!:D

The body including the eyes was a major reason for getting the HF unit last week for $28. I can teach the kids how to use it faster than a hand file too.
