Curve Point Extension Blade #1
Official Hyde specifications
Dimensions
4-3/4" x 3/8" x .035"
PRODUCT FIT · IS THIS THE RIGHT TOOL?Straight answers. If it's the wrong tool for your job, we'll say so.
The guidance below describes applications and limitations. For a match to your particular job or an existing tool, ask us to confirm fit.
If the station's cuts are straight slits and trims with the occasional corner, the bevel-point extension blade is the right tool and the curve point only gets in the way — its swept edge wants a line that turns.
Not heavy or dense stock under high pressure — at 20 gauge it is a follower, not a commander; dense material that pushes back wants a stiffer 18-gauge blade.
Not a heat blade — for high-friction synthetics that round carbon edges, the HSS blades are the answer, not a light carbon curve point.
Not a handled personal knife — the riveted Paris Curve (55300, sibling guide) is the one-owner version of this geometry; the 57320 is its station-fed counterpart.
Steering through curved and concave cut lines — radiused trims, swept seams, inside arcs — where a straight blade bridges or digs. It keeps one rolling point of cut on the line the whole way around.
How is it different from the bevel point at the same gauge?
Only the point shape. Both the 57320 and the 20-gauge bevel-point 57060 are light .035" blades; the 57320 curves to steer, the 57060 runs straight to a working corner. There is no other difference to sell.
What width is it?
The listing and fact sheet say 3/8"; the printed catalog lists the #1 at 5/16". We carry the conflict and won't guess. It fits the wood handles either way.
Is it stiff enough for dense material?
No — at 20 gauge it's a follower for light, conformable stock. Dense stock under pressure wants an 18-gauge blade.
Do I need a special handle?
No — any of the line's four flat-sided wood handles takes it.
