What does "405" mean?
Nobody's record says — not the catalog, not the listings — and this store won't guess . It reads as a Hyde pattern designation, like the code numbers on the industrial blades two lines over, and it stays undecoded until Hyde says otherwise.
What gauge is the blade?
The catalog's own page gives a gauge label and a decimal thickness that contradict each other on Hyde's own ladder — so this store prints the figure the record agrees on, .072" thick, and no gauge number at all. That refusal is deliberate and stands until Hyde reconciles it.
How long is the blade?
The catalog and our listing title disagree (3-1/4" vs 1-3/8" — possibly full blade vs cutting edge), so this page names the conflict instead of picking a side. The thickness is the settled figure; length waits on Hyde.
Is it insulated for electrical work?
No. No insulation rating, no live-work listing — the wood handle is tradition, not protection. Dead, locked out, verified, then the knife.
Why not just use a utility knife?
Feel and depth control, mostly — the scoring skill rides on a rigid maintained edge that telegraphs depth. But the honest answer runs both ways and it's in section 5: keep whichever edge you'll actually keep sharp.
Will it strip Romex?
It will — ring and slit works on NM like anything else — but a dedicated NM ripper is faster and safer at that one repetitive job, and this page recommends it for production. The knife earns its place on everything the ripper doesn't fit.
What's the blade shape?
Undocumented — the trade's cable knives run sheepsfoot to hawkbill, and Hyde's record doesn't adjudicate this one, so neither do we.
