Mr. Ayoob, thank you for your response to my question, and I am humbled to be in the presence of an acknowledged master. I am sure my fellow forum members agree that your participation here is deeply appreciated. I'm sure that your busy schedule does not allow frequent postings, but we would be glad to hear any future contributions from you.
In your description of the applications of your knife, I failed to determine if the grip you describe is the so-called "hammer" grip, with the thumb curled over the middle of the index finger, or the classic saber grip. The design of your knife seems to lend itself to the saber grip, with its choils and traction grooved thumb ramp.
How effective would your knife be in the hammer grip? And, when speaking of the reverse grip, that is, with the knife's tip pointing away from the bottom, or pinky, side of the hand, do you refer to the edge outwards or inwards?
This discussion prompted me to dig out my own Spyderco Ayoob from the knife drawer. Frankly, it had been retired shortly after purchase due to my awareness of the pikal trend as exemplified by South Narc. I was fortunate to obtain your knife from Smokey Mountain, as the design was being phased out. At a rather cheap price as well, I'm glad to say. I seem to have obtained a later version that has handles made of a material unknown to me. They have an almost bead-blasted quality, without the "slipperiness" of the earlier version, as referred to by others on this thread. I am glad to re-discover this knife, and I'd love to hear about any application it might have in reverse grip, edge in, and forward hammer grip.
