On the tuffheads. Keep in mind they are HC (high carbon) 420 SS, same stuff as in higher grade knife blades and sharpen just as well for me and Not the harder than H 440 SS which I believe the Ashby heads are?
I have an antler handle with arrow section that I use to sharpen heads. The Tuffhead and a flat diamond block works pretty good for me. Grizzlys I have to whang away with a file for awhile first.
Some REALLY NOT NICE PERSON walked off with my paper wheel out of the garage...so hand sharpening this year. Eh, still works. Something about the hand/file sharpening fits me and my "old and aint broke" attitude it seems.
Picked up some 190 (five I think, have to relook lol) Grizzlys, right bevel and have 3 160s (left bevel), 2 pretty used.
Nice heads, work great, 190s are the old style and "wrong for me" bevel (right) but I have RW feathers around
Never put the newer 200 grainers up on my priority list and now they arent around.
Grizzlys are definately the more economical so hope they "come back" but I like the Tuffhead just a bit better.
Betting critters wont be able to tell the difference LOL.
File wise, I think for decades Ive used "old cheap files" and better late than never, figured out that is a MISTAKE unless you have lots of patience.
File suggestions requested, yet like heads......some of the prices drive me nuts LOL
Old.....Poor.......bullheaded. Whatta combo!
God Bless
