I need serrations on my work knives and have a few plain edge knives I want to cut some serrations into.

My plan is to use a 1/4" shank spiral cut / tear drop shaped carbide bit (i'll post pics as i go) chucked into a high speed air die grinder
which will be mounted into a vice. I'll then be able to use both hands to manipulate the blade into the bit.
First i'm going to try this out on a couple beater blades i have as a dry run, hopefully getting it down to where
I will be able to serrate a Pocket Bushman and another folder which has 440C.

Anyone know any other methods or members here on BF who do this, and what is the process?

Thanks in advance.
 
Serrations - not so popular i suppose. Wonder if richardj is into them, i'll have to get in touch with him.
 
Okay. The die grinder idea may work if you are carefull but the better way is to use a chainsaw file (it is round and not tapered and you can get them in various diameters) and alternate with a jeweler's round file of half the size. This gives you that big/small/big scallops you need for good cutting. Some start with a checkering file for the spacing and then finish with the other files. It is better to take a little time here so you don't endure a lifetime of pure ugly.

Note****The serrations only get cut from one side- not both. The back side gets a flat honing after you smooth out and polish the scallops.
 
A good while ago I did some serrations with chainsaw files to mixed results. The serrations are pretty easy to do and keep even with a chainsaw file they come in a few sizes ,mostly easy to find in the regular sizes that serrations come in. Just get some files and decide the angle you want and draw them out with a sharpie and it helps to have some kind of guide clamped to the blade to make sure you don`t slip, otherwise they are easy and kinda fun. Also after you make them they are easy to sharpen with 2000 grit auto sandpaper wrapped around a correct sized steel/brass rod drawn backward at the right angle. I hope this helps:)

Thanks for reminding me, now i'm trying to decide about alternating big/small/big or same sized as I have used both styles.
 
It's also gonna be cool bcz I can serrate only as much as I want, as in 1/3 of the blade or less. Most manufacturers seem to go overboard and use up 1/2 the freakin blade with serrations, tired of that!
