The BAZ™ Knife Jig Handle V4.1 (Suits Tormek KJ Jigs)

The Amazing and Unique BAZ™ Knife Sharpening Jig Handle V4.1 bolts straight onto self-centering knife jigs such as the KJ-45* and KJ-140*, found on many leading water-cooled sharpening systems, giving a firmer, more natural hold for smoother, more consistent sharpening strokes.

Based on thousands of hours using systems of this style, this handle was engineered through real-world experience — not theory. It’s the strongest and most refined version yet, featuring a 100% solid-fill design tested under extreme stress levels.

Ready to bolt on with no modifications, no glue, no hacks required. Just a heavier-duty, better-balanced handle that makes every pass on the grinding wheel calmer, straighter, safer and more predictable.

The new Version 4.1 features a thicker, more robust 100% solid shaft, slightly wider thumb cup for even more stability and strength and is 5mm longer to suit the rare situation where you might want to sharpen a very narrow blade such as a very small well used narrow pocket knife.  

⚙️ Key Benefits

• More control, less wobble – thumb-cup and grip geometry give stable pressure and cleaner strokes.
• Comfort that lasts – neutral wrist position reduces hand fatigue during long sessions.
• Bolt-on simplicity – installs in about 60 seconds; no cutting or gluing.
• Built to work – solid, heavy-duty feel that turns your jig into a tool, not a toy.

🔩 Features → What You Feel

• Wider thumb-cup dome → precise tip control and pressure without finger strain.
• Wider guard / flange → confident palm index; keeps your hand off the wheel splash.
• Super-reinforced neck → firm leverage with almost zero flex.
• Lightly textured finish → secure grip, even when wet.
• Ambidextrous → identical control left- or right-handed.

🕒 60-Second, 3-Step Install

• Remove the factory handle from the jig — be careful not to lose the springs.
• Seat the BAZ™ Hybrid HD Handle V4.1 on the metal boss and align holes.
⚠️ Install the small-hole side first, double-hole side last. Be gentle.
• Finger-tighten both bolts, then snug evenly.
• Always make sure the second (larger) tightening screw is loose and fully undone before tightening the number 1 (smaller) screw to grip the blade as snug as possible before securing it with the second large screw.
