kme sharpening jig

[RecurveJim]

I reground the bevel on my grizzlies to 25 d.Will this jig keep it at 25?

Jim -- I don't know if you're talking about the standard KME broadhead sharpener, or something new Ron is working on. But the standard jig is a little piece of amazing ingenuity. It is mounted on a swivel with a roller that runs over the stone, so that when you press you fringer down on the front of the jig, it adapts to whatever angle you have on your head. Short answer: it will handle any bevel angle great. I love mine. dave

It will not keep the angle at 25 degrees but truthfully it doesnt matter.  If you reground the bevel to 25 then the KME will simply sharpen the edge to a razor and you will not lose the twisting/bone crunching effect of the 25 degree bevel.  

The sharpening only goes up to a negligible part of the edge.  

BTW the angle of sharpening is somewhere around 30 degrees with the grizzly accoriding to Ron himself.

Jim,

Reading your post, it sounds like you have ground the bevel and now are wondering if you can use the KME?  You can use it but you will be at around 30 degrees like Troy said.  Ron told me the same thing.  

I have made a fence/jig to put the KME on while I lower the blade of the Grizzly to the sanding disk.  That way both the grind and polish will be at the same angle.  I just got it made so will have to test it out      

Gotta agree with Troy also that if you have ground the bevel at 25 and use the KME to only polish a small edge at 30, you will be sharp and the bevel will still due it's job.  If you have any questions, give Ron Schwartz, KME's owner a call.  He is a great guy to talk to.  Leave a message if you get the machine.  He is busy but does call back.

Ray and Troy -- do you guys have the same KME that I do? Or maybe you're tightening it to a locked angle situation. As I said above, mine is hinged so that the clamp holding the blade is free to "find" the angle of the edge and adapt to it. At least with single-bevels, which have rather broad edge bevels compared to double-bevels. Oh well, you guys sort it out ... I'm going elk hunting. dave

thanks for the replys,Ijust cant seem to get em shavin sharp and everyone raves about the  kme so I bought the kme kit.On the video it says to only snug the hinge so dave makes sense,and even if I get just the edge shvin im good.

Dave,

Same KME - not tightening the jaws beyond swiveling.  The angle that we were referring to is not the length of the edge, which is what the self alignment aids in.  We were referring to the angle of the bevel itself, which is determined by the width of the broadhead clamped in the jaws, from it's edge on the sharpening stone to the roller underneath the tool.  From the side view of the KME, you see a triangle in the points described if you connect the points made with the edge of the bh, the roller and top of the KME directly above the roller.

A wider broadhead will create a shallower angle.  The Grizzly is not that wide and thus the approximately 30 degree angle from the sharp edge to the shoulder of the bevel on the top of the blade.  

For our purposes, the consistency of the bevel and thus the sharpness, is more important than the few degrees of angle different than what Dr. Ashby determined as optimum.  In most of our scenarios, the angle difference will likely not be noticed.  The KME helps keep the consistency in sharpening, especially the hard heads!     :D

I hope you inhaled the wild today!  Looking forward to hearing about the hunt.
