The Hayauchi Pole Saw is constructed of aluminium alloy. They are oval in shape which provides extra strength and rigidity and minimises bend when fully extended. This gives the user greater control over the direction of the blade when cutting.
In addition there are two locking systems which again work to assure structural rigidity of the extended poles:
locking pins/buttons - the primary pole locking mechanism
friction clamps - the secondary pole locking mechanism.
The two systems are designed to work together. Spring-loaded locking buttons allow multiple length adjustments and safety friction clamps hold the extensions firmly in place. This dual locking system allows 100% of the effort at the handle to be effectively transferred to the blade.
This Hayauchi blade is manufactured from SK-4 carbon steel and cut out by laser. The taper-ground profile reduces drag and directs more usable energy to the cutting edge.
The Hayauchi utilises Silky\\\\\\\'s proprietary 4-RETSUME teeth technology which literally means four rows of teeth. As a result, the teeth are set in such a way that there appears to be four rows of them which leads to faster, more aggressive and easier pruning. These saws can easily be used for rougher cutting and heavier tasks as they can rip-cut, cross cut and slant-cut.
The Hayauchi Pole Saw blades are chrome plated which helps protect against rust and sap as well as providing additional strength. This also helps extend the life of the blade.
Hayauchi Pole Saw blades are not manufactured using electro impulse hardening and as such can be re-sharpened using a feather edge file. This should help extend the life of the blade.
