Knife Grinding Jig

Featured Replies

I saw a jig made of angle iron and bolts. I believe it was CJS Knives. I was at a resale shop the other day looking for some angle iron to make one when I saw a heavy duty hinge. Here is what I came up with. post-16150-0-21373900-1327797518_thumb.j Take the hinge apart and cut off the last pin receiver on the end. post-16150-0-20990300-1327797537_thumb.j Insert a bolt and nut. post-16150-0-83268800-1327797586_thumb.j Set at desired angle. post-16150-0-80428200-1327797594_thumb.j Attach knife. post-16150-0-86547500-1327797614_thumb.j Grind. post-16150-0-86874900-1327797637_thumb.j The knife was made from a piece of cable, that I hope turns out well. post-16150-0-43619600-1327798151_thumb.j The jig seems to work pretty well. It is alot better than my free hand style. I'll post the finished knife soon. Thanks for looking. Jamie

thanks for posting that the simplicity is great, a" why did i not think of that moment."

I guess I'll have to try that - I've been looking at some type of jig since I have trouble with freehand grinding. VERY hard to get the grind line straight and even on both sides. That is so simple. THANKS!!!

Hand ground blades done free hand are not that hard at all. Just most folks do not put enough effort into learning. If youi get a twenty foot bar of mild steel and cut it all into blades and grind them all you will be close to being able to grind..If yoiu can find bp # 0235 It shows how I finsih knves free hand, and it is so easy even I can do it.

Rich,

I searched for bp # 0235 but couldn't locate it. (Not enough letters?) Is there a keyword or phrase I could searh for?

Ken,

I discovered that imperfections (dimples or thinner areas) affect the way the grind looks. On this blade both sides look similar but are not exactly matched. I can live with it! Live and learn!

Wow great tip!!! :D

I like this jig idea, my only question is how can I make it suitable for a hidden tang knife. I'm almost thinking zip ties to hold it by the tang but that doesn't seem quite solid enough. Any ideas would be great.

Cotton,

I have two small "C" clamps that work pretty well for that.

You could get another piece of steel, match the screw holes in the hinge and use bolts to turn the whole thing into a clamp.

Awesome Tip good for Newbie's and ol makers of knives as well .

Cross pein, That's exactly what I was thinking; get two hinges with no holes and take one side off of one and cut the pin holes off the bottom then drill out the holes together and just use some thumb screws and lock nuts to tighten it. Then again, you gotta love the simplicity of Jamie's C-clamps idea. What I use now has worked alright for me but this jig idea takes out so much human error from it.

Rich,

Thanks for posting the blue print for hand grinding. I'm gonna give it a try.
