The Amarillo is a fine choice for anyone who likes flippers with a 2 3/4 inch blade, as I do.
It is sharp, well-made, with a well-centered blade, and flips well. The brown scales are attractive and a nice change of pace from black. They have a good feel and are moderately grippy. The Amarillo is small and light-weight with a deep-pocket clip.
IMO, it lacks only gimping and chamfering on the blade spine.
The Amarillo is a good candidate for pocket-EDCing.
As for the Sante Fe, I ordered it by mistake. The headline description still says 3-inch blade. Why hasn't Tangram corrected this? The Sante Fe blade is clearly 3.35 inches long.
