Frequently Asked Questions (FAQs)

1. Do pull through sharpeners damage knives?

Even the adjustable ones are not well suited to all knives. Electric pull through sharpeners remove way too much metal and shorten the life of your knife by years. Ceramic wheel sharpeners tend to take chips and chunks out of thin Japanese blades.

2. What is the difference between ceramic and carbide knife sharpener?

Carbides provide quick edge setting, and the specially shaped ceramic stones are designed to give you a razor sharp edge on either standard or serrated edges. A fold out, tapered round, diamond coated rod is designed for sharpening serrations and small gut hooks.
