My favorite 2.5" knife (Boker Blackwood Pipsqueak):
I had to send my first one back because the lock was loose. Boker replaced it within 2 weeks and I've been happy with the replacement. Blade profile is great, and keeps an edge really well.
If you like the above Boker, check out the Spyderco and Michael Burch collaborative knife, the Chubby with a 2.3" S30V Blade and Titanium Handles with Carbon Fiber inserts. Love the blade profile (that starts from a 4.5mm thick stock!) ...
Lots of YouTube videos on the knife as well ...
Most discount places sell it for about $220. It's on sale this week at KnifeCenter and KnifeWorks for $135-140, shipping included, supplies limited ...
