Mr. Lee,
I know you (at least occasionally) monitor posts on this newsgroup, so I wanted to throw out a suggestion, scratch that, I wanted to *beg* you for a new Veritas product.
There is currently one manufacturer in the Milky Way Galaxy who makes registered mortise chisels in true Imperial/fractional sizes: Lie-Nielsen. I'm sure they are wonderful tools...just like Lee Valley/Veritas they do excellent-quality work.
They are currently backordered for four months. I called, and they said that demand so far exceeded supply that four months was the best I could even hope for.
There is only one other manufacturer out there making something even close, and that's HMG out of Germany...they sell exclusively on Hartville Tool's website. I bought one because the catalogue description said "square." Only to find out their idea of square is actually to bevel the sides about 4 or 5 degrees inward. They are nice chisels, and measure spot-on at the stated size, but there not registered to say the least.
So I hereby grovel at thy feet to throw us poor yanks a bone and sell some real imperial *registered* mortise chisels.
Can I get an Amen from the group here???
