Advanced Blade - GKS Series
USAGE
Any type of wood-natural wood, synthetic wood, plywood, drywall board, etc.
Hollow Ground with Standard Set Raker Tooth Pattern
A hollow ground blade means that the tooth edge is thicker than the top of the blade, as per diagram (a), this makes the normal set of a blade unnecessary.
The main advantage of this design is the reduction of friction when cutting and a superior cut, similar to that of a planed surface. (see diagram (b)). The term “Standard set” refers to the angle of teeth being the same along the full length of the blade. The Raker tooth design has Gullets or hollow gaps set into the length of the blade see diagram (d), the Gullets eliminate jamming of the blade when cutting softer or sappy types of wood. The sawdust is more efficiently removed from the cutting zone, reducing the friction and increasing the efficiency of the cutting action by keeping the blade in better contact with the material being cut. This blade has been impulse hardened and will last three times longer than a conventional none impulse hardened blade. (see diagram (c)).
Diagram (a) - Taper Ground Blade
Hard chrome plated finish is rust proof, friction free and produces a smooth cut surface similar to a planed surface. Teeth are sharpened by whetstone to produce a super sharp cutting edge far superior to the cut of saws with teeth sharpened by conventional filing. The sharpness is equal to that of a high quality knife.
Diagram (b) - Cuts like a knife
Hard chrome plated finish is rust proof, friction free and produces a smooth cut surface similar to a planed surface. Teeth are sharpened by whetstone to produce a super sharp cutting edge far superior to the cut of saws with teeth sharpened by conventional filing. The sharpness is equal to that of a high quality knife.
Diagram (c) - Impulse hardened teeth
Permanently filed teeth have been subjected to precision controlled electronic impulses (Impulse hardening); which heat and harden only the cutting edge of each individual tooth, making sure the razor sharp cutting edge stays sharp cut after cut. Typically an impulse hardened blade will last three times longer than a conventional none impulse hardened blade.
Diagram (d) - Raker Tooth design
When sawing soft, sappy wood the sawdust can build up between the teeth and the surface being cut. This decreases the efficiency of cutting. To avoid this happening Samurai have machined Gullets or gaps in the teeth which allow the sawdust to escape from the cutting zone.
