First I'd like to give my condolences regarding Mr. Engeldrum's son. I will say a prayer.
As for Tanto knives, I had always wanted the original Tanto, however, at the time I got the Trailmaster instead. It is my understanding that the Tanto was always AUS8, until the newly designed Recon Tanto came out. That is, until reading this thread

- I thought they also had 5 3/4" blades as oppossed to the full 6" of the newer versions. Mine is the 6" stainless guard model. A buddy of mine used to have the 7 1/2" magnum Tanto (I think it was SMIII - not certain; it was in the early 90's) and it too had Stainless steel guard & pommel.
HM Hoek said "I've always been tempted to get a tanto, but my SRK has served well in its absence". I hear you, however, my wife, God love her, got me both a Tanto & an SRK several years ago for christmas the same year

I love my Tanto but it is more of a drawer queen - the SRK gets all the 'action' - including being the fixed blade I take with when I travel (in my checked luggage).
I had no idea about Buck having originally made any CS knives or there being any handle material other than Kraton or stag or cord wrap... Anyway, Very Informative thread - Thanks!!!
