Species, log grade and peeling temperature determines the bevel angle of the knife face. The bevel angle of veneer knives varies from 17 degrees (hardwood species with thin peels) to 23 degrees (softwood species with hard knots). A face width of 3.95 cm strengthens the knife edge and increase its resistance to damage(Baldwin 1981). However, it tends to produce deeper lathe checks than does a wider face. The peeling veneer separates from the bolt and bends away from the knife at a sharper angle, creating deep lathe checks which in turn reduces veneer resistance to breakage during handling. The optimum bevel angle is the widest knife face having sufficient resistance to edge damage. The wider the face the tighter the veneer.
