WoodRiver Low-Angle Adjustable-Mouth Block Plane

What this tool adds

What this tool adds to your bench

This is the compact block-plane option for small-part trimming, easing an edge and end-grain work. Its low-angle bed and hand-sized format give it a different role from a bench jack with front and rear wooden grips. Consider it when the work needs a smaller tool that can register on the part you are fitting, rather than choosing a larger plane simply for its broader-looking body.

The adjustable mouth changes the opening ahead of the cutting edge, while the rear adjustment knob controls the blade position. Those are separate controls. The knuckle-style cap is the distinctive rounded upper grip visible in the photograph. The body is stress-relieved ductile iron and the blade is high-carbon tool steel, with a stated 12-degree bed and 25-degree blade bevel.

The iron measures 1-5/8 inches wide and 0.125 inch thick. Use those as blade dimensions, not as a statement that a similar-size spare from another plane will fit. The maker specifically recommends sharpening before use. This matters if you are assembling a first hand-tool kit: allow for edge preparation and learning the adjustments rather than relying on a promise of a particular finish straight from the box.

Choose this low-angle model for the compact block format. Compare the No. 62 if you want a low-angle jack with two-handed bench grips and a longer sole. Choose the open-front chisel plane when access to a proud plug or an inside trimming point is the central need. Overall-size figures differ between the listing fields and maker specification, so confirm the footprint before buying a fitted storage case.

Choose for your actual work

• Separate the small block-plane format from a longer jack when comparing workpiece support and gripping space.
• Confirm the actual storage footprint before ordering a fitted case; do not treat the largest listing dimensions as verified packaging measurements.

Fit checks & limits

• For a close-fitting case, confirm the actual body dimensions. The maker gives a 2 × 7-inch footprint, while the listing’s 7.85 × 3.75 × 2.75-inch fields do not clearly describe the same measurement.
• No maximum cutting depth is confirmed; the listing’s 2-inch cutting-depth entry should not be used to plan a cut.
• Order a replacement iron by confirmed model fit, not matching width alone.

Use & care

Sharpen the blade before use as recommended by the maker. Follow this model’s instructions for the mouth and blade controls; they adjust different features.
