The 10585’s blade remains stationary while its acetone-resistant metal sheath slides up to protect the blade, or down to expose it. Held in a durable reinforced nylon housing, the installed ceramic utility blade protrudes at just the right angle to effectively cut boxboard and cardboard, without putting the user at any unnecessary risk. The blade’s rounded tip prevents accidental punctures and its edge features Slice®’s finger-friendly® grind, which is safe to the touch. The ambidextrous carton cutter’s slim, lightweight handle fits easily in your palm or pocket. Blade options include the 10526 (installed) and the 10528 (pointed tip). As with all Slice tools, the blades are non-conductive, non-magnetic, chemically inert, and will never rust.
