I.P. Hyde Curved Lip and Straight Lip knives. The only old Hyde catalog I’ve seen that contains knives like this is this one, page five. It looks like the number (00, 0, 1, 2, 3, 4) refers to the blade length.
“These modern popular knives feature Hydex High Carbon Alloy Steel Blades expertly hardened and tempered, precision ground to perfect cutting edge. Each knife is individually hand honed. All blades are riveted to fibre finished handles.”
What’s a fibre finished handle?
