Oh yeah. Super Sharp, but super thin edges that will simply not hold up to any contact with bone or other hard substances.
Does a nice job of cutting rope, flesh, etc. though.
I have a box full of chipped ones.
The A-2 trailguides seem to hold up better than the 1095 stuff.
The older BJK convex line (Mamba, Warner-Moran, Anaconda) are much thicker than the USA produced stuff at the edge.
Much more durable for hard work.
"Blackjack Sharp" was a sales technique pioneered by CEO Mike Stewart.
They were/are the sharpest factory knives ever produced. People bought lots of them for that reason.
Unfortunately they are also the most fragile at the edge.
The good news is that the carbon blades re-sharpen very well on a sharpmaker and will get <almost> as scary sharp as the factory edged version.

Anthony can you determine how thick the blade is just behind the bevel and what angle it is the ground at?
L6STEEL, what do you mean by "apple seed edge"?

My understanding is that "apple-seed edge"="rolled edge"="convex ground"="moran edge".
L6STEEL, without wanting to hurt your business, how do you resharpen a convex edge? Slack belt?
All the new Marbles knives are convex edge. Are the Marbles more durable than the USA blackjacks?

Cliff:
the Blackjack Classic Blades series were
convexed to "sharp" that is zero ground from the top with no secondary bevel.
The edge is very thin.
Mike Stewart once remarked to me that it was somewheres in the neighborhood of 11 degrees
per side but since it is convex I am not sure how he arrived at that figure.
The knives seem to do much better at closer to 30-35 degrees included angle.
Sharpmaker works fine.
If you would like a loaner to test drop me a line. I have several in need of resharpening in A2 and 1095 that you can experiment with.]
FYI, I will be out of town until Sunday Jan 23.
Thanks

I picked the term "apple seed edge" up from Kit Carson in the chat room. I was having the same problem. I was making my edges super sharp, but too thin because I was grinding them edge up. Now, thanks to Kit's help, I slack belt them edge down to get a nice convex edge.
Kevin, after I have the edge right, to really get the blade sharp, I buff the edge with white rouge on a loose muslin wheel. I've heard it gives the same effect as stropping leather. Never tried that, but I do know that buffing really makes a slick cutting edge that lasts.Take care Forumites! Michael

Thanks a lot! I live close to Don Fogg though and he said if I would bring it by, he would fix it. I really do appreciate the offer though.
Anthony-
Send me your knives and I will be glad to play with them! Do you have any BlackJacks or Beckers for sale right now? I would love a Trail Guide or Squad Leader or....... Matter of fact, I think you got a Squad Leader from me once.
Thanks to all for the replies. As stated above; appleseed = moran = convex edge. Look at the cross section of an appleseed and you will see why.
