Busse Zero Tolerance Satin Jack Busse LE & Zero Tolerance Satin Jacks

Story - Zero Tolerance series was first introduced in 2001. Though ZTSJ(Zero Tolerance Satin Jack) doesn't quite fit in the whole story. Which in short was, that the grinder by mistake ground certain number of blades to 3/16" instead of 1/4". Now that definitely made happy a whole bunch of Busse fans, since many were asking for the thinner versions of Busse Combat knives. Anyway, ZT series included 3/16 thick NO, SH and BM. Obviously I wouldn't miss that sort of an opportunity to get yet another Busse blade, and placed an order, back in summer 2001. Hopefully I'll get them sometimes soon. The thing with ZTSJ is that it's standard 1/4 thick in stock, but features the same tan canvas micarta handles and Zero Edge geometry. In the end, we've got a beautiful knife.


 - ZTSJ is similar to SJ LE, except the clip point, basically that's it. ZTSJ if you decide to use it is a great general utility use, medium blade. Since only total of 100 blades were produced, less likely that I'll use it anytime soon, though I like it a lot, and the temptation may get too big one day :)
    Overall, this is a ZTSJ is a very nice knife, quite simple, no fancy details, except the zero edge geometry. Rugged and tough, it'll withstand practically anything you'll have to throw at it. After all it that "Nuclear Toughness" from Busse Combat. ZTSJ came with Kydex sheath. Blade is secure and won't fall out when held upside down. Although it's really difficult to pull the blade out. IMHO too secure you know :)


 - Straight, flat ground, clip point, 6 inch long blade, perfectly fit for the light and medium utility use. Though considering its 1/4 thickness, weight and the famous INFI steel properties ZTSJ will fare very well with heavy duty works, including prying and chopping. Clip point has its advantages for finer cutting tasks, though is weaker than spear or tanto points for prying, but I think ZTSJ will do juts fine. Blade material Busse proprietary INFI steel, which is a very good steel. It combines very good toughness with equally good wear resistance. That combo makes it really exceptional material for heavy duty knives. Though I'd love to have a folder in INFI :)


 - ZTSJ has the same handle as the rest of SJs. Straight handle, which I find very comfortable and versatile. Though some it to thin. Well, there's no perfection :) Others consider eHandles to be too thick, etc. It's all too personal. Though the straight handle makes it unique in the current line of the Busse knives. There are no other straight handled knives in the current Busse combat knives line. Officially SJ knives have, what Busse describes as The multi-fluted micarta handle marries a superior grip with raw aesthetics. Paper micarta and those grooves provide secure grip. Even when your hands are oily or wet. on all Busse LE blades the grip feels comfortable and secure, thanks to those grooves.
