WHY THE PRICE IS JUSTIFIED

The price buys a stainless channel, purposeful indexed grip and tape-splitter rather than branding. It is a better value for routine shipping work than a decorative metal knife.

DESIGN & ERGONOMICS

The finger groove gives clear orientation and the bottom tape splitter saves opening the main blade for tape. It is practical-looking rather than luxurious.

LONGEVITY

The stainless channel is the key durability feature; blades are replaceable. The ABS body is durable for normal work but not a substitute for an all-metal demolition tool.
