[It's less than $10, right? I would like Veritas or Lie-Nielsen 15 times more expensive. This is the one I have. It's less than $10, did we talk about that? Yes? Good. Seen that way - ] Somehow it didn't occur to me that there should be a cap screw and not just a set screw. (Let's blame the cognitive problems of old age and illness, shall we?) Tools like this need to be optimized. Level the sole, sharpen the blade. After that it worked perfectly, even without the screw. Then the adjusting screw broke off. I have another bolt that fits so I'm still in business but for now I'll find another bolt to replace the missing head bolt. Either buy this one and fix it and then replace it in X years, or spend $150 on a V or LN and never buy again.
