I don't have this specific Nealy, but I have a couple of others and hBud's multicarry system, rare earth magents and all, is the best I've seen. Really.
My Nealy blades have been superb, but mine are Meier clad damsacus with a 52100 core. Razor sharp and just about perfect blades.
I've thought about the specialist, and the Pick. I have a bias for customs and for a neck knife, the sheath has to be very reliable. Is it worth the difference in dollars? That's a personal choice. For a really hard use knife...well, i did a Fehrman for super slim and super hard use... but if the Boker was particularly solid, I wouldn't hesitate.
