Sharpening grinder knives

post #1 of 26
Thread Starter 
Do any of you sharpen your own grinder knives? I've always been under the impression that it couldn't be done, at least not by the average guy. I do it anyway and have had pretty good luck with my results. All I do is clamp a knife into my vise, and with a 6 in. mill-bastard file, lightly file on the bevel side of each blade of the knife. I strive to maintain the original angle very closely. Then I hit it a few licks with a small stone. I don't touch the "face" of the knife, the part that runs against the plate. I can definitely see a difference in my grinding after this touch up. Of course, I've not done anything to my plates, however, I am inclined to think if you had a very flat, large enough stone, or a machinists granite plate and some fine emery stuck to it you could hone them down a bit as well. Anyone else had any success with sharpening either of these essential parts?

In 6 years with my last grinder I have not done a thing; we are very picky with the meat making sure bone nor bullet go through. With that being said, is my grinder knife slowly loosing it's edge and I am not noticing it?

Last season we purchased a backup knife and still didn't feel the need to try it. My thought was to bring the grinder knife into a guy I bring hunting & fillet knives, lawn mower blades, saw blades, etc. into for replacing the edge and sharpening ( I do the final honing on the hunting & fillet knifes). I have all the tools to do it myself, I just do not trust myself to a professional that does this daily; price is fairly inexpensive, am I in the wrong for not going totally DYI?

Well thats kind of what I figured as far as cost goes. A new knife isn't terribly expensive, so not out much if I screw it up. Mine had about 10 plus years on them, and also about 300-400 lbs. of meat per year. It just seemed like mine were slowing, and getting "gristled" up more quickly than they should. I'm pretty meticulous about trimming before grinding too. I think it does just kind of sneak up on you. I figured I sharpen all my other cutting tools and knives, including hoof knives, wood chisels, crosscut saws, axes, etc. this can't be much more difficult. So far I don't regret it a bit.

I have learned to sharpen my own cutters-blades,chain saw-etc-(woodworker that I be) I have a triangle sharpening rig that I bought 30 years ago-many different # stones-very rare I let anything go to where I need a file,but times u do,than the stone,30* angle is a norm on alot of things-and never touch the trailing edge,cept with a emory cloth-if u don't trust yourself than learn! if not trust another!It don't take much to ruin a good edge.
