I'll chime in with the normal "try using a search on this forum and testing forum".
That being said I owned a Basic 3, still own a cobalt dive Basic 3, and a Basic 1.
My opinion is they're nice, cut well except for when the thick blade profile will bind against what is being cut. The cast handle makes them somewhat less comfortable than knives with other kinds of grips.
Shop around, Boye knives from Boye are 2X price from other sources.
Well I own one, so I guess that says something. At least one person thinks they are worth the price.
The blade is very stout and strong but goes to an edge that is very sharp. My only dislike about the B3 blade is its width from edge to spine. This makes it a less than wonderful paring knife. It works extremely well for hard cutting though.
The bare handle sucks in my humble opinion. It is slippery, and its I-beam shape can be uncomfortable to boot. Wrap some parachute cord around it though, and it becomes quite useable. The down side is that you then have to get a new sheath made for it because it won't fit in the one from Boye with cord wrapped around the handle.
In the final analysis, with the handle cord wrapped, and a Mike Sastra Concealex sheath, the B3 is a strong, great cutting, excellent urban tactical in the style of say a Stryder knife, but prettier. Mine has a nice bamboo pattern etched into the blade.
