Hyde Tools 20610 3-1/2" Flooring/Drywall Knife

Pierce with the point, lay the blade into the draw, pull toward you and let the inside curve gather the material — same as the wing. The long blade adds momentum and tracking through thick goods, and it adds sweep: mind the longer arc the edge travels, keep the off-hand and kneeling leg out of the exit line. Leverage is edge leverage, not tip leverage. The extra inch multiplies cutting bite, and it also multiplies the lever arm on the fine long point — twisting a buried 3-1/2" blade side-loads the spur harder than the same twist on a 2-1/2". Prying, snap-line work, and tear-out belong to the short-point 20250 and the Black & Silver 20550; the big knife's size is not armor, and this guide won't pretend it is. Depth: the open point cuts what's underneath — sacrificial surfaces under rough cuts, captured hooks (42200/67090, other lines) wherever the substrate must survive; a deep blade only makes that discipline matter more.

High-carbon cutlery steel ⚑(per the p.40 catalog block; provenance registered above) on the line's maintain-not-feed contract, with more edge to maintain than any sibling: slip stone or dowel-backed abrasive drawn along the inside curve following the full sweep, burr stropped off the outside, flat bench stones never used alone — they flatten the curve's belly. Keep the point; it starts every cut in both of this knife's trades. The drywall designation accelerates the honing schedule, and wet floor work demands the dry-wipe habit — neglected carbon steel blooms rust. The owner who won't stone an edge has an honest consumable alternative in the utility line's blades, stated here rather than implied.
