The origin of the hawkbill or pruner blade hearkens to a time before there was a cutlery industry. The design began as a harvesting hook for grapes and other produce and a net/rope cutter. A larger size was built for pruning fruit trees. For Linoleum and carpet, this blade was the original blade of choice to cut easily. And as electricians found, it served as a great wire stripper and cutter.
The reasons for this blade’s great utility is in the design of the blade, allowing for easier cutting when drawing backwards. The hawkbill pocket knife comes in many sizes, but typically features the prominent long curved hawk bill shaped blade. Sometimes it comes with a thumb-hole open, instead of a thumbnail pull, again for easier use while working.
