Gyokucho 651 Blue Hard Fine-Pitch Ryoba — 240 mm

What this tool adds

What this tool adds to your bench

Choose the 651 when a finer-pitch crosscut edge is the useful addition to a general-purpose Ryoba. The selected listing presents it for hard or abrasive woods such as maple and oak. It still provides two grain-direction edges, so match the rip or crosscut side to the cut rather than assuming that hardwood work always uses one edge.

The maker’s 2025 model table gives a 240 mm blade, 0.45 mm plate and 0.73 mm reference kerf. Its pitch figures are 1.3 mm for the fine side and a varying 3.8–2.4 mm for the rip side. Pitch is the spacing between teeth; it is not the same unit as teeth per inch.

The selected listing describes impulse-hardened teeth and interchangeable blades. The maker separately identifies the complete wooden-handled saw as 651 and its spare blade as S651. Choose by that model relationship instead of assuming any 240 mm Ryoba blade has the same attachment or tooth design.

Compare this finer-pitch format with the Suizan SR-001 for a general rip/crosscut pair or the Temple backed saw for dedicated fine ripping. Exact teeth-per-inch and net-weight figures differ across the available data, so they are not used as settled comparison filters. The fine-pitch model and maker’s scoped plate, kerf and pitch figures remain the useful specifications here.

Choose for your actual work

• Compare pitch and grain direction instead of choosing from an unsettled TPI field.
• Use the complete-saw versus spare-blade codes when ordering parts.

Fit checks & limits

• Exact TPI and net tool weight are not settled across listing and maker references.
• No high-speed-steel alloy claim or universal replacement fit is adopted.
• Maker carton quantities do not describe this one-saw consumer offer.

Use & care

Select the maker’s S651 replacement relationship; length alone does not establish compatibility.
