Razorsaw Replacement Blade — 270mm Kataba 15TPI (fits RS-450)

Blade: 270mm × 0.6mm, 15 TPI

Format: Replacement kataba blade (single-edged)

Fits: RS-450

Made in: Japan

Replacement blade for the 270mm kataba (RS-450). Single-edged, 15 TPI, 0.6mm kerf — same geometry as the original.

Razorsaw blades are impulse-hardened, which gives the teeth far longer working life than a conventional saw. When the edge finally goes, the blade gets swapped out and the handle stays in service. Every Razorsaw is built that way: handle for life, blade as a consumable.

This is the matching blade for the RS-450 — the 270mm crosscut kataba. Single-edged, no back spine, so the blade flexes and cuts to any depth. 15 TPI is the general-purpose kataba pitch, biased to crosscutting but happy in lighter ripping work. The blade tapers slightly toward the spine to reduce friction on deeper cuts.

Razorsaw — Japan’s craft-saw standard

Razorsaw has been crafting blades to traditional Japanese standards out of Tokyo since 1969. Long edge life and replaceable design are the two things that make these saws a long-term tool rather than a consumable.
