Is this the right tool for your job?

✕DO NOT FORCE THE FIT
  • Not a shingle knife: steep-slope asphalt work belongs to the 22310 and 22320, and no buyer correctly hesitates between a granule-armored slope and a membrane deck — the line doc calls this the line's cleanest discrimination, and this guide agrees.
  • Not a sheet-flooring hook: the 67090 shares the hydetools "Hook Knives" shelf but is a captured-throat linoleum pattern — hooks an edge, pulls, cannot plunge — a different geometry for a different trade.
  • Not a membrane production cutter: long field cuts belong to shears and dedicated cutters, and an honest detail knife does not pretend at them.
  • Not a seam probe, on the record as it stands: the prodder reading is live but unconfirmed ⚑.

How the pros run it

01

Care instructions inherit the steel gap ⚑

until Hyde confirms the blade's steel, the safe regimen is the carbon regimen. Membrane work is solvent-and-adhesive-heavy chemistry — primers, seam cleaners, bonding adhesives — and all of it sits on steel, so the blade gets wiped dry after contact and stored with a film of oil. The edge itself is the easiest maintenance geometry in the whole line: a short straight hone — fine stone, steady angle, burr stropped off — with none of the curve-following ceremony the hooked patterns demand. The notches are the one feature not to maintain by stone: Hyde says they are hand-filed, and .062" is a printed dimension — dressing them is re-manufacturing, not sharpening. Keep the honing to the plain edge and leave the filed feature as made. And because this is deck work, not slope work, the roofing line's stance rules relax to bench sense: the piece supported, the pull away from the holding hand, the small blade doing small cuts.

Asked at the counter

BUYER QUESTIONS ANSWERED BEFORE THE CART, NOT AFTER THE RETURN
What is the notch for?
Hyde does not say, anywhere we can cite . Two labeled readings exist — a seam-probing feature (the catalog calls the knife a prodder, and probing welded seams is real membrane QA) or an edge-engagement feature dimensioned near the 60-mil membrane class — and neither is confirmed. If your purchase depends on the notch doing a specific thing, ask us to put the question to Hyde first; that is the honest answer.
Is it a hook knife?
It is filed on Hyde's Hook Knives page and printed straight in the catalog's own name. Filing is not geometry: the blade is a straight pattern. The naming implies a hooked sibling exists somewhere in the book ; it is not this knife.
What are the blade dimensions?
3-1/8" × 1/2" × .065" — the only full dimension row printed for any knife in this line.
How many notches does it have?
Hyde's sentence says "notches," plural; the name prints one dimension, .062". The count is not stated .
What steel is it? What handle?
Neither is stated in the accepted record . The catalog photograph and a specialist distributor both point to a hardwood handle — treated as pending confirmation, alongside a store-taxonomy conflict that files this SKU under replacement blades .
Will it cut shingles?
Wrong roof. The 22310 and 22320 exist for that trade; this knife's world is flat, welded, rubber and thermoplastic.
Who actually buys this?
Commercial-roofing and industrial shops that already know the K-pattern. The knife's record is thin; its clientele isn't guessing.
