I received a Spehar 2" blade and Chipbreaker in the mail on Saturday. What a difference this combination makes in my #4! I spent about 10 minutes honing the blade and installed it in the plane......Worked fanstatic. I made a large pile of white oak shavings (sorry no pics this time).
Vlad is a great guy to work with, he responds to EMAIL quickly and has a great product.
I'm in no way connected, but though I would give MHO about his plane blades.
