Like our Low Angle Bench Planes, these planes all have the blade bevel up. Low Angle Block planes have the blade bedded at 12Â°. We grind a 25Â° bevel on our block plane blades. This works well in low angle planes for end grain and general purpose work. Standard angle block planes have the blade bedded at 20Â°. The bedding angle, plus the bevel angle, equal 45Â°, which is the same cutting angle as a bench plane and gives a very good finish on flat and difficult grain. Higher cutting angles will give excellent results in difficult or highly figured woods.
Ok, so we left off discussing secondary edge bevels. If you have a scandi grind with a 30 degree inclusive bevel, and a flat grind with a 30 degree inclusive edge bevel, then the same exact angle meets the material being cut. The sharpness potential for both types of grinds is identical.The edge's resistance to wear is identical.f field maintenance is of any concern at all, scandi is hands down the best grind. There is nothing easier than a knife that has its own angle guide built right in. You lay the bevel on a flat stone (which will last you decades longer than a sheet of sandpaper) and push.
