Cutthoat Broadheads

[Jason277]

Hello all, I just started using Cutthroat Broadheads 125s . Im really liking the way they are tuning. I was just looking to see, who else uses them and how they are sharping them. There is not alot of info on youtube regarding sharping etc... Thanks Jason

I use the 250 grain with my recurve.

Kme broadhead sharpener and strop on cardboard. Work on the bevel side the whole time until the end. Then just light strokes alternating between sides on the finest stone until the burr is gone.

I think when Rms gear does it in the shop they use a paper wheel.

I have a worksharp 3000 the one with the wheel on top. I can get them to a mirror polish with that at 8000 grit. I just leave them on the shaft and do it freehand. The bevel of the blade is wide enough to know by feel when its flat on the wheel. Just don't let your finger drag on the wheel, gets a bit hot!

Forgot to mention, check out the scary sharp sharpening method. Woodworkers use it to get crazy sharp chisels. It's basically the same thing as a cutthroat blade.

I will check it out!

The bevel from the manufacturing process will have minor differences in true over its length. Its worth it to true this edge.
1) true the edge bevel using a course diamond stone. Take care to maintain the factory bevel. Run the bevel along its long axis back and forth so its fully supported on the stone. This is the best way to maintain control when free hand. Later you can touch up the trued bevel across its length if you prefer that method.
2) Once satisfied that the bevel is true go to a fine stone until the bevel is uniformly shiny.
3) then lightly dress the opposite side to remove what is left of the serrations from the grinding process when the bevels were made at the grinding wheel. 3 or 4 very light passes should do it.
4) Strop on leather or any suitable surface. I am able to get them shaving sharp in about 10 minutes a head.

After this its super fast and easy to touch them up. Like after you pull it out of the toad you just arrowed.

I tried hand sharpening mine, but I just can't do it! I pulled out my Edge Pro Apex system and worked my way through the stones from 400 up to the 8000 grit...mirror finish and crazy sharp and they fly like darts!

Just started shooting the 125's this year. I haven't ran them through anything yet, but tuning them was a breeze. I'm shooting them out of a compound and was able to get them to group right with my field tips out to 85 without a ton of effort.

As for sharpening, it took me a while, I eventually bought the KME broadhead sharpener. I couldn't do it free hand, I just don't have the touch or the patience. I have been able to get them to shave hair using that and finishing them stropping on cardboard with some polishing compound on it. However, I wouldn't consider them "scary sharp" just sharp enough. I need to buy some better stones if I'm going to get them scary sharp. If I were to do it over again I would probably just break down and buy the KME knife sharpener set instead of the Broadhead sharpener.
