There are too many variables to say, but I can say, without confirmation of testing, that the Krenov style planes I've tried to use were inferior. Now, I didn't make them and there are several reasons they failed and/or were inadequate, but there you go.

I think good Krenov style planes have been made, as many attest; and if I were making molding planes, the first I'd try would be Krenov/Todd Herrli style.
