As you might expect we’ve had a fair amount of interest in running this course, in fact some folk have been asking for it for a couple of years now. It therefore gives me great pleasure to announce that we are currently in discussions with Mark Harrell at Bad Axe Tool Works to finally make it happen during London International Woodworking Festival. Ferrying people and equipment between continents to deliver a class is no mean feat but I’m convinced it’s the right thing to. Desperate measures require drastic action. Mark is unquestionably a man at the top of his game when it comes to saw sharpening. Time spent in bis company could turn out to be a game changer for anyone serious about hand tool woodworking.

Description: MASTER SAW SHARPENING & MAINTENANCE SKILLS AND BUILD YOUR OWN BAD AXE WITH MARK HARRELL.
Let’s demystify saw sharpening and master the skills required to restore your vintage saw collection with confidence, and build your own Bad Axe with Mark Harrell, owner of Bad Axe Tool Works.
Mark’s five-day course enables tool resellers, entrepreneurs and hobbyist woodworkers at large to maintain, retension, retooth, hammer-set, and sharpen-to-joint hand, panel, frame and backsaws across a variety of pitches. The course culminates in a graduation exercise in which the student builds his/her own Bad Axe Precision Carcase Saw (included in course tuition).*
Instructional methods center on historical techniques and best practices employed by craftsmen from over three centuries of western traditional sawmaking. During this class, you will learn how to:
- Assess, evaluate, restore and maintain an array of vintage backsaws and handsaws.
- Build your own inexpensive saw sharpening vise and maintenance system.
- Hammer-set and sharpen-to-joint carcase, tenon, panel and handsaws across a variety of pitches.
- Re-shape an asymmetrical toothline with differently-sized files to achieve consistent rake, bevel and symmetry.
- Maximize a saw’s performance based on a thorough understanding of how plate gauge, pitch and sawtooth geometry work together for a desired cutting effect in both softwoods and hardwoods.
- Graduation exercise: build your own Bad Axe 14” (35.5 cm) Precision Carcase Saw.
*Note: all files, vises and sharpening equipment will be provided on-site. Students may keep the files and 4 training plates provided by the instructor to take home for continued practice.
