Just grab the ZT0630 for $145 shipped today from SMKW. Newer year model and more useful blade shape imo. The wave feature is great and makes the blade ready for use as quickly as a fixed blade on the draw. 0630 is still tip strong, although not a tanto. Both the 0620 and 0630 are discontinued but readily available.
