I have an 0561. Mine is #250 and I have had it for a long time, probably one of the earliest on BFC. Its an epic knife and is a real workhorse EDC. ELMAX is ideal if not perfect for this knife. I've cut 4k psi hydraulic line, drywall, shaved schedule 80 PVC, hardwood, the list goes on. It doesn't chip, it rolls and it doesn't ever seem to really need a sharpening. I may touch it up on the 1k Chosera every few months, but it shaves hair with just a strop and that stone. Its so perfect I wouldn't even bother with the S110V version. Mine is SOLID and has had zero play since day one. I can't even force any play and it sits at about 50% these days.
It may never leave my rotation and its THE knife that gave ZT the balls to be world beaters with all their limited/expensive offerings. Of course there are better knives, and there always will be, but the 0561 is in an elite group for production knives.
Its not my most expensive, or rarest, or even best looking, but its a fantastic knife for the money and its 85-90% of a real XM at 1/3 the cost.
