The Spyderco Delica to me has always been the quintessential pocket knife for every day carry (EDC) use. It’s light, strong, and well built in Seki, Japan. Normally made from high quality VG-10 steel, it can also be had in higher quality ZDP-189 steel.
But they like doing limited edition runs of certain models, and they’ve seen pretty good success with the Aogami “Super Blue” variants of their lightweight FRN (fiberglass reinforced nylon) knives. In fact, anything in super blue ranges from hard to impossible to find.
In 2016 most of those same models: Delica, Dragonfly, Stretch, Ladybug and Manbug will see another Japanese “super steel,” HAP40, which is a powered tool steel made by Hitachi.
These Delicas pretty much sold out in minutes as each dealer made a small quantity of them available. I think the total run is 1,200, so this is going to be repeated a few more times until they are all gone or demand drops off. Since the super blue Delica is an incredibly rare beast, I would expect no less from the HAP40 Delica.
