The DongCheng HD110218 18mm Heavy-Duty Snap-Off Utility Knife is built for severe construction environments, flooring installations, warehouse shipping operations, and industrial manufacturing. Featuring a composite hybrid handle forged from durable die-cast aluminum alloy, high-impact ABS, and non-slip TPR rubber, it offers tremendous rigidity and comfortable grip ergonomics.

Fitted with an ultra-tough 0.5 x 18 x 100mm SK5 high-carbon alloy steel blade (8 segments), it withstands high cutting pressure without edge fracturing or bending. Spanning 160mm in total length, it delivers excellent pulling balance and cutting stability across dense materials like heavy carpets, rubber flooring, and drywall. Supplied in a protective slide blister pack.
