Gen 2:  Nakishi Stick (New Age Knapping-Ishi Stick) has one slight change over the Gen 1. One end of the Ishi Stick has been designed for Indirect Percussion. A 7/32 hole has been drilled through the Ishi stick to allow you access to extract the 4 gauge copper wire from either side. A 7” length of hard copper wire is provided with this kit. The Gen 2 Kit provides up to 9 working tip. The 171/2″ Delrin Nak-Ishi stick extends over 20″ and is designed with 1, 1/2″ x 5 1/4” aluminum modules that extend out to 3″ from the handle. This allows you to work on smaller projects without the 1″ Delrin handle obstructing your work or view. Included is a 1”x6 ½” Delrin short handle that shares the two modules in this kit. The first module has a 9/64″ bore for 8 gauge copper wire or 16d smooth box nails. The second module is bored half way for 8 gauge and half at 11/64″ for 6 gauge copper wire. Each module has double set screws at each end for extra working pressure. Both Delrin tools are double tapped at each working end. Tips included with this kit are 8 & 6 gauge standard copper wire, 6 gauge hard copper wire (until I am no longer able to find it), 16d smooth box nail and a horseshoe nail for notching. I clip the heads off of horseshoe nails and with a little file work I can use the 8 gauge side of either module for notching without having to buy another specialized tool for this purpose. This kit comes with 2 Hex Key and 1 extra stainless set screw for each size used. (one 8×32 x 1/8” one 8×32 x 3/16” and one 1/4”-20 x 1/4”)
