I also like the style and lines of the Centofante knives, however, as MBC blades they are lacking in a number of areas. First and most importantly, their locks are not MBC rated. The stresses of full-power ballistic cutting are severe and a sturdy lock is a must.
Secondly, the grind of these blades leaves the blade tips pretty thin and fragile. For a gentleman's folder, they are great and allow very detailed work with the point. For MBC use, they are simply not stout enough.
Finally, the handle shapes of the Centofante models provide little traction that would help keep one's hand from sliding forward during a thrust. Although a proper grip makes guards and finger grooves unnecessary, the smooth lines of these knives provide little extra security during thrusts.
In my opinion, the greatest quality of the Centofante designs in the straight cutting edge that extends all the way to the point. This allows for low-drag, back-cut-style cutting with the primary edge and consistent forward pressure during cutting strokes. I like this a lot - so much, in fact, that it will be a major feature of the Yojimbo design that is currently in development with Spyderco.
Thanks for your comments.
