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. Reviewers confirm it earns its keep specifically on garden tools, which matches the title even though the listing sits in a Knife Sharpeners category.
- 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.
What buyers say
From Amazon customer reviews.
Reviewers say it noticeably sharpens pruning shears, axe and hatchet edges, and kitchen or pocket knives without needing to take tools apart, and several call it easy to use with clear instructions. The recurring complaint is that the dial's blade-setting numbers are raised in the same orange as the housing, making them hard to read; one reviewer found it only adequate without elaborating.
Strengths and trade-offs

Performance notes
Reviewers describe passing a tool through the relevant slot roughly twenty times per edge for a noticeable improvement, and several confirm it handles rusty, dirty pruning shears without disassembly. 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.
