Overview
This is a 7-in-1 sharpening tool sized for EDC or camping gear, built to bring an edge back to axes, hatchets, machetes, pruners, shears and knives with one device.
Rather than a single knife sharpener, this is a multi-slot tool that shifts function by blade type, aimed at gardeners and outdoor users who maintain several kinds of edges at once.
- 7-in-1 sharpening tool
- Model ON-GTKS-01
- Sharpens axes, hatchets, machetes, pruners, shears and knives
- Tungsten sharpening elements
Who it's for
Works well for gardeners and outdoor or camping users maintaining pruners, shears, axes and knives with one small tool. Less useful for someone who only ever sharpens kitchen knives and has no garden or outdoor gear to maintain.
Pros and cons
- Sharpens knives, pruners, axes and shears alike
- Compact size fits EDC or camping gear
- Works on rusty tools without disassembly
- Built with tungsten elements for regular use
- Dial numbers blend into the tool's own color
- One reviewer found results only adequate
Performance notes
The recurring build complaint is that the dial's raised setting numbers are molded in the same orange as the tool body, making them hard to read at a glance.
