I am mystified. Pop knows knives and steels. But my expience with INFI has been opposite of his. I just touch it up with a ceramic rod or a strop. Here's what Jerry Busse says about his steel:

Sharpening
INFI's high level of chip resistance also makes it the easiest steel to resharpen by hand that we have ever encountered. I personally fall into the category of "hand sharpening challenged". I've heard tales of those who can sharpen ball peen hammers to a razor's edge on an Arkansas stone in less than 5 seconds flat. My experiences have always been to the contrary. The spine of the knife is usually sharper than the edge when I'm finished applying my magic stone sharpening technique. One of the great features of INFI is that simply stropping away from the edge (the way a barber strops a straight edged razor) on a ceramic stick is basically all that is required to resharpen INFI. Since you're not chipping steel off the edge there is no need to grind any steel away. This feature of INFI will, likewise, allow you to keep the same overall profile of the knife for a much greater period of time.

But I agree with David on one thing, there's no need for a Busse INFI folder. My Rat Trap in S30V is just fine! <img src="/ubbthreads/images/graemlins/grin.gif" alt="" />
