Last but not least is this short video I took of the upcoming Spyderco Tighe Stick, designed by Brian Tighe. Eric Glesser gives a quick table top preview of this stunning knife. Again, sorry for the poor video quality. Proper pictures of the Tighe Stick prototype can be found in this post.
I have no information on the planned pricing or availability/shipping dates of this knife, it is still a prototype. These Spyderco production prototypes usually become available within a year.
