You know, I think the planing stop looks cool but for it to be truly fuctional the way it was meant to be, it needs to have saw teeth on it to grip the work. I think in the age of end vises its not really needed. But I still think it would be usefull if you had a jig for planing thin pieces that clamped in your vise, one of those could use the support of a planing stop. But then again if you make it a little extra long you could just back it up with a hold fast.
