Advanced Blade - GKC Series
Any type of wood-natural wood, synthetic wood, plywood, drywall board, etc.
Hollow Ground with Raker Tooth Pattern
Traditional wood saws have their teeth bent out or “set” so that only the teeth touch the wood and there is less friction between the wood and the side of the blade. This style of blade needs to make a wide cut and therefore takes more time and energy.
Taper ground blades give the same effect but have and even taper from the teeth to the back of the blade and this allows the blade to be thinner (see diagram (a)). A thinner blade makes cutting faster and easier.
The curve of the blade has been designed specifically to make cutting above shoulder height easier. The precision ground teeth have been designed to keep the cutting action consistent along the full length of the pull stroke. This design is unique to Samurai and makes this blade probably the most efficient and user friendly in the world.
The Raker tooth blade has Gullets or 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 removed more effectively from the cutting zone, reducing the friction and increasing the efficiency of the cutting action.
Diagram (a) - Taper Ground Blade
Computer controlled grinding machines produce Taper-Ground blades with greater thickness on the teeth edge making the set of the teeth unnecessary.
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.
