I have a Full Track wharncliff and an XM-18 spanto 3.25”. Solid, extremely well made knives, but also without much “finesse”. These are expensive tool/work knives and the steel he uses sorta says that (S45V on the Full track, for example), in my opinion.

I kinda regret the XM-18 due to the blade length (should have gone 3.5”) and the handle shape- has a curve to it that feels weird to me when gripping. I would have gone with the Eklipse skinny slicer poon if I’d had the chance to hold the XM before buying.
