Sharpening system for workshop use promising accurate, cool-edge results with repeatable angles. Bucktool Variable Speed Sharpener suits woodworkers and knife makers who want controlled speed and effective heat management. Is it the right upgrade for a small workshop?
⚡ At a Glance
- • Sharpening Precision: Variable 90–160 rpm control paired with wet grinding for consistent edge geometry
- • Best for: Woodturners, woodworkers and knife makers working in small workshops
- • Not ideal for: Users who require ultra-fine polishing beyond the supplied 220 grit capability
Variable-speed wet grinding uses a 250 mm aluminium oxide wheel, a 200 mm leather polishing disc and a water tank to prevent overheating. Two-position universal jig and reversible rotation make repeatable bevels straightforward, with Bucktool backing the unit with a two-year warranty.
Consistent bevel angles - with the two-position universal jig
Two-position jig adjusts both horizontally and vertically so tools are held at repeatable angles during grinding. The jig secures chisels, knives and carving tools for accurate edge formation.
Repeatable grinding angles reduce rework and speed up setup between tools, giving reliably consistent results for batches of blades or chisels.
Cool, controlled material removal - thanks to the water-cooled wet grinding system
A dedicated water tank feeds the 250 mm aluminium oxide wheel, keeping the steel cool while grinding, and the variable-speed motor runs from 90 to 160 rpm to match removal rate to the task.
Lower heat reduces risk of temper damage and steel deposits, letting users remove metal efficiently without overheating edges.
Refined finishing after grinding - with the 200 mm leather polishing disc and 220 grit capability
Following coarse grinding on the aluminium oxide wheel, the leather disc and wet/dry 220 grit workflow allow for a controlled polish and edge refinement.
Polishing on the leather disc tidies burrs and improves cutting performance, leaving tools ready for use or for a final stropping stage.

❓ Frequently Asked Questions
Q: Can the rotation direction be reversed?
A: Yes, the power switch can be pressed up and down to reverse the direction of rotation.
Q: What speed range does the motor support?
A: The variable-speed motor runs between 90 and 160 rpm, allowing controlled material removal for different tools.
Q: Does the system prevent overheating during sharpening?
A: Yes, a water tank supplies cooling for the wet grinding system to keep tools cool and help prevent steel deposits.
🏆 Our Verdict
Suitable for woodturners, woodworkers and knife makers who want controlled, repeatable sharpening in a small workshop. The system combines a variable-speed motor, water-cooled wet grinding and a two-position jig for reliable edge preparation. While initial outlay may be higher than handheld options, durable construction and a two-year warranty make it a sensible long-term workshop investment.
