I will continue to assemble and sell the titanium N_Dura 4 folders pre-installed on a new Spyderco Endura 4 folder until those grips are gone. I do not sell the N_Dura 4 grips alone becasue they are dificult and frustrating for most customers to properly install. You kind of need a surface grinder.
Thanks to the many thousands of customers worldwide who supported the WilkinsGRIP line for so long.
