Ovolaco™ Door Hinge Jig
Restore Your Chain in Minutes
Clamp it onto the bar and grind tooth by tooth with the included stones — a full chain takes about 2 minutes, no power needed and no removing the chain from the saw.
How to Use It?
Four Steps to a Sharp Chain
- 1
Open the sharpener — slide the two halves apart.
- 2
Attach it to the chain — line up the two holes on the guide bar and the chain.
- 3
Close and lock it — push the two halves together until the lock clicks in.
- 4
Squeeze gently — press down until the chain touches the whetstone, then run it along the bar.
Anyone Can Do This
No experience needed. Just clamp the sharpener onto the bar, close and lock it, then gently squeeze until the chain touches the whetstone. Stable, guided, and hard to get wrong — even the first time.
A dull chain doesn't just cut slower.
It kicks back.
A dull chain doesn't slice through wood fibers — it compresses them. It grabs, bounces, and rides across the surface instead of cutting clean. When the nose of the bar catches instead of slicing, the saw is driven back toward the operator. That's kickback — and it's the mechanical reason most serious chainsaw injuries happen.
A sharp chain cuts. A dull chain grabs. The Ovolaco restores the exact factory cutting geometry that keeps the chain slicing instead of catching — in under 5 minutes, without ever taking the chain off the bar.
This isn't about saving $10 at the shop. It's about finishing the job with both hands.

We Got Answers!
Do I need to remove the chain to sharpen it?
No. The Ovolaco™ Chainsaw Sharpener clamps directly onto your bar. The chain stays on — you attach it, lock it, and press down until it touches the whetstone.
Will it work with my chainsaw brand?
Yes. It's compatible with most standard chains including Stihl, Husqvarna, Echo, and Oregon, across the common pitch sizes and bar lengths.
I've never sharpened a chain before. Is this hard to use?
Not at all. Open it, attach it to the two holes on the bar, close and lock it, then gently squeeze until it touches the whetstone — the guide keeps every tooth at the same angle.
How long does it take to sharpen a full chain?
Most chains take just a few minutes tooth to tooth.
Does it actually get the chain sharp — or just "good enough"?
It restores a clean, even edge on each tooth using the built-in whetstone. Most users find it cuts noticeably better than a chain left to dull between shop visits.
How many times can I sharpen one chain with this tool?
A chain can typically be sharpened several times before the teeth wear down too far. After that, you'd replace the chain — but by then you've already saved on shop fees.
Is it safe to use?
Yes. The lock and guide keep the tool in place while you sharpen, so there's no risk of slipping or over-grinding. A sharp chain is also a safer chain — dull chains increase kickback risk.
Is it worth it if I only use my chainsaw occasionally?
A single local sharpening usually costs $8–$15. The Ovolaco™ pays for itself within the first few uses — even if you only cut a few times a year.
