Silky Tsurugi 400mm Straight Sheathed Saw Medium Teeth No.452-40 [Total Length & Blade: 580mm / 400mm / High-Carbon SK95 Steel / 1.8mm Heavy-Duty Slim Blade / Tool-Less Genki Grip / Yellow Accents / Aluminum Sheath Included]

Description

Manufactured by Silky (UM Kogyo) in Ono, Japan, the Tsurugi 400 Medium Teeth (452-40) is an extra-long, high-precision straight-blade sheathed saw engineered for deep reach and maximum stroke efficiency in tightly packed branch unions, dense canopy crotches, and crowded foliage where standard wide-blade saws cannot enter.

Named after the traditional Japanese long sword (Tsurugi), this saw features an ultra-narrow blade profile designed to slip effortlessly into tight V-shaped crotches without snagging adjacent limbs. To prevent bending over its impressive 400mm length, Silky utilizes an innovative 1.8mm Heavy-Duty Blade Thickness, giving the long, slender spine exceptional structural rigidity and zero flex when cutting through thick branches. Crafted from premium SK95 High-Carbon Steel with Mirai-Me Technology, its medium tooth geometry (10 teeth per 30mm) offers a perfect balance between rapid cutting speed and smooth finish across greenwood, fruit trees, and dry timber. With Impulse Hardened Teeth, the cutting edge maintains razor sharpness up to three times longer than standard saws.

The full-tang structure is housed in Silky’s tool-less Genki Grip (featuring yellow accent locking clips), a 2-piece vibration-dampening rubber handle that can be disassembled by hand in seconds for quick blade swaps without tools. Comes equipped with a high-tech lightweight Aluminum Sheath featuring a 4-roller system and a finger-trigger detent safety lock (yellow trigger) that holds the long blade securely in place, even when working upside down in high climbing scenarios.

(Compatible replacement blade No.453-40 sold separately).

 Maximum Long-Reach Slim Profile: 400mm slender blade reaches deep into dense crotches and high canopy unions with surgical precision without damaging opposing stems.
