Frequently Asked Questions
-
Absolutely. The course teaches universal sharpening principles — edge geometry, steel behavior, abrasive science, and technique. We demonstrate on TSPROF systems because that's our equipment, but every concept applies whether you're using stones, a KME, a Wicked Edge, or sharpening freehand. Many students start the course with no equipment at all.
-
YouTube gives you fragments. One creator's technique contradicts another's. You piece together a method from 50 videos and end up with gaps and bad habits. This course is a single, structured system — 23 lessons in logical order, each building on the last, designed by the engineers who build precision sharpening equipment. It's the difference between googling symptoms and seeing a specialist.
-
This course starts from literal zero. Lesson 1 is 'What is a bevel?' By design, we assume no prior knowledge. The structured, weekly format means you build skills progressively — you won't be thrown into advanced techniques before you've mastered the fundamentals.
-
Those tools aren't the problem — the missing knowledge is. This course teaches you the 'why' behind sharpening: why your edge rolls, why your bevel is uneven, why your results are inconsistent. Once you understand the principles, any tool becomes more effective. Most students report dramatically better results even with equipment they already owned.
-
30-day money-back guarantee. Watch every lesson, do the assignments, and if you don't feel the course was worth it — full refund, no questions. We've had less than 3% refund rate because the content delivers.
-
Because we've spent 10+ years engineering the physics of edge creation. We don't just sharpen knives — we design the machines that sharpen them. That gives us a deeper understanding of angles, abrasives, and steel behavior than any hobbyist YouTuber. We built this course to create better sharpeners, not just to sell more systems.
Your knives deserve better than a dull edge
You already invested in great blades. Now invest some time in the skill that makes them perform.
