Overview
A kitchen counter or workshop bench is where this metal, angle-guided sharpener does its work. You set the bevel with the included digital angle indicator, then step from coarse diamond through fine ceramic and finish on a leather strop.
Precise angle control is the reason to own it: the digital indicator lets you return to the same bevel every session, and the diamond grits run from reshaping to refining. Serrated blades and scissors are not mentioned anywhere in the listing. It also takes up real bench space and is heavy to move around.
Who it's for
Knife owners with a mix of kitchen, pocket and hunting blades get one system that handles all of them at a chosen angle. Someone who only needs a fast refresh on a single chef knife will find the setup slower than needed.
Pros and cons
- Digital indicator sets the exact edge angle
- Diamond grits span reshaping to refining
- Leather strop included for final polish
- Handles small pen knives too
- Bulky and heavy to store
- Takes longer than pull-through sharpeners
- Serrated blade support not listed
- Needs a stable bench or counter
Performance notes
Edge quality depends on holding the set angle through every stroke, which the guided frame and indicator handle for you. Working through the diamond grits before the ceramic and strop removes the burr left by the coarser stages. Skipping steps leaves a rougher edge that dulls sooner.
