Hyde Tools 20450 2-1/2" Long-point Vinyl Knife

Vinyl under tension turns hesitation into tears; the draw should be continuous, moderate force, wrist locked, letting the curve do the holding. Angle: steep to pierce, then laid down into the cut — if the blade climbs out mid-pull, the edge is dull or the angle too flat; more muscle is never the fix. Depth: the open point cuts whatever is under the sheet, so rough cuts happen over sacrificial surfaces and in-room cuts ride the crease, not the subfloor. Warmth: vinyl handles cold better than linoleum ever did, but a warm sheet lies flatter, creases sharper, and trims cleaner — acclimate the roll in the room when you can. The point is not a pry: the fine long spur that starts every cut dies by twisting and levering; snap-line and demolition side-loads are the 20250's design brief, not this knife's.

For carbon cutlery steel, sharpen the inside curve with a slip stone or dowel-backed abrasive drawn along the sweep, then strop the burr off the outside face. Use flat bench stones only with care; by themselves they flatten the curve’s belly and spoil the hook profile. Keep the point keen above all—in vinyl work every cut starts with a pierce, so a rounded point hurts performance faster than a dull belly. Wipe dry after working over fresh adhesive; carbon steel can rust where stainless steel resists it. For disposable edges, use consumable 42200 hook blades in a utility knife.
