Sharpening Warehouse Inventory

Famous For Selection and Service

We offer many different types and dozens of brands of sharpeners. In fact, we have over 1,500 different sharpening items. Our warehouse is fully stocked to meet your specific sharpening needs. If you need a complete sharpening system, a hard-to-find sharpening stone, or just a replacement wheel, if it is related to sharpening, we probably have it.

We ship everything we sell. We ship Monday through Friday and all in-stock orders placed by 2:00 p.m. CST are shipped the same day. By shipping quickly, we're able to get your items to you faster. That is how we do business and we would be happy to earn your business.

To whom it may concern, I got my DMT Aligner Kit today and I just cant say enough about it and my experience with sharpeningsupplies.com. I got the extra extra fine stone along with the DMT deluxe aligner kit. My favorite knife now is as sharp as a scalpel. First Class Company and First Class Products. Truly a pleasure doing business with you.
