Great for chisels but it will leave you with nice sharp corners on the edges of the plane irons that will leave "tram lines" when smoothing a large surface. If you are only truing wood narrower than the plane iron then this is not a problem. If you need to smooth a large surface than those corners need to be knocked off. I manage this with mine by applying pressure on each side as there is just enough tilt to allow this to happen.
Veritas have overcome that problem with a Camber Roller
