Anyone ever tried this?

Denis Ch�nard, Orl�ans, Ont.

>Using a standard bench plane (bevel down, 45 degree frog) on difficult grain lumber, tearout ensues. Given that the blades are commonly sharpened at 25 degrees, has anyone tried to just flip the blade over, giving a 70 degree angle of attack? David Charlesworth reportedly grinds back bevels to get to that kind of effective angle, and I assume the back bevel makes for a stronger edge. I'm just wondering if the edge can take it without modifications...

Never tried it myself, just wondering if anyone has...

Side question, are there terms used for effective angles beyond half pitch (60 degrees)?

>Depends what you mean by 'standard bench plane'. This practice is standard procedure for standard Chinese bench planes since at least a few hundred years. They also use the wedge behind the blade on occasions.
