I`m giving away using shell for a while, to costly and too much work ,so I decided to try my hand at this,believe me ,when there is no flex in the scale material ,getting the wedge exactly right is a fiddly process.
I had to adjust the wedge and re-pin the razor 6 times to get it, don`t laugh ,I`m obviously a slooooow learner

For better or worse this is it ,the scales are red deer antler and the wedge is beech the blade is a W&B
Kind regards Peter
