Ok this is not to bash Razor Edge's mouse trap honing system, this is just what happened with one of the 3 knives I used it on.
I get the Razor Edge's mouse trap honing machine! Try the SP-10 that had a so-so Edge, it made it shaving sharp! Sharper than the factory edge! A cheap Winchester 4" blade came out freaking sharp! So I tested the CS Marauder, still sharp as heck.
Well I move to the SP-51 and try it...duller than a butter knife with slight nicks in the blade. My theory is the angle of the grind isn't good for it, it couldn't even cut paper any more! I took a great factory edge from OKC and well made it a big butter knife, so there went its debut in the woods. Hence my reason for having two decent blades, so use the SP-10 that did a good job. When I practiced my Batactitonical skills against Tyrannical Botanicals by Batacitoning them! The SP-10 did great, it cut through a 6-7 inch dead pine tree and I did some Batacitoning some kindling for the old farm house.
When I took the knife to Razor's Edge, I am close by them, I showed them my SP-51 by running it over my hand the dullness of the blade. "How did you do that to it?" the Grinding guy asked me, he honed it on one they have there, it was sharper but one side was still not as sharp as the other side but still not as sharp as factory edge. So I paid a small fee and he touched up the knife so its super freaking sharp than my other knives now! I know I'll get it duller with use, but now its going to have an even better start! My sharpening stone hasn't made it back my way from hunting season from some one who needed it sharpening his cutting knives. Oh over there some one said "That's a good looking knife" :thumbup:
The one theory I think that happened was is the SP-51 wider grind angle might have some thing to do with it. But this is total speculation and I'm not well edumacated in blade and edge geometry interactions with honing devices. So if some one can tell me what happened or how totally wrong my theory is I'd sure like to hear about it.
That Razor's Edge Mouse Trap sure worked wonders on my other knives! I'm keeping it even if I did blow the SP-53 or RTAC2 budget on it! (Was still deciding on which one to get next.)
Edit: I have to add that some how really odd things happen to at times, maybe this was one of them things where some how I just did the impossible again with not knowing it was possible...again.
