Funny the things I'll think I need.
The "Schrade" "Heritage" is almost a copy of the Selkirk, but I "need" it because the edge has more curve and the blade is ca 3/8" longer than the Selkirk.
Or I need the buck Alpha Guide because the edge is more curved than the Selkirk (even though the blade is a little bit shorter, like 1/8"), and it would be lighter than the Selkirk, without the integral end-plates.
And the Nieto Criollo is not wildly dissimilar to any of the above, but the 6" blade makes the point seem a little distant for non-stabbing purposes, and the edge could be more curvaceous, and a straight heel would be safer than the Spanish notch on a blade this narrow.
My BPS Savage and a couple of Argentinian verijeros aren't wildly dissimilar, either.
Still, I'm sure I'll buy more similar unnecessary knives, though not right now.
