Very fast. Feels like new.

Happy with process and result

Great knives for edc and their blade sharpening and replacement service is a plus.

Will definitely purchase from them again, great knives and customer service!!

Reasonable in size, very sharp, and excellent quality. I had my knife engraved, and while I was initially a bit concerned about the quality of the engraving design, I was thoroughly pleased with every aspect when I received the knife. I really like the automatic function. One piece of constructive feedback: the packaging could have felt a bit more authentic, though this is a minor detail. Overall, I’m very happy with my ZT 0556.
