Official StoreTenvik Chainsaw Sharpener
I've tried electric sharpeners and manual files, but nothing compares to the speed and accuracy of Tenvik. I was clearing fallen trees after a storm last week and hit a hidden wire. The chain was ruined. I pulled out the Tenvik, spent five minutes touching up the teeth, and got right back to work. Absolutely brilliant design.
2 weeks agoHeat about six cords a winter and used to pay a shop to sharpen. Paid for itself the first weekend. The guide keeps the angle honest so every tooth cuts the same.
3 weeks agoNever sharpened a chain in my life before this. Clamped it on, cranked the handle a few turns, and the saw was throwing real chips again instead of dust.
4 weeks agoWorks exactly as advertised. Took me two teeth to get the feel for how much pressure to use, after that it went quick. Wish the hex key was a little longer.
5 weeks agoBought it for my husband and ended up using it myself. Not being able to see or feel what you're doing was always my excuse — the guide removes that entirely.
3 weeks agoGot three so each of my saws has one in its case. No hunting for the file, no taking the chain off. Bits still look new after a full season of storm cleanup.
6 weeks agoDull chain nearly kicked back on me last fall and that was the wake-up call. Now I touch up the teeth before every job. Takes a couple of minutes.
2 weeks agoSolid metal, no flex in the clamp. Only note is that the instructions are brief — watch how the burr lines up with the tooth once and it's obvious.
7 weeks agoMilling firewood on a small property. Went from replacing chains twice a season to sharpening the same one over and over. Rust hasn't touched it in the shed.
5 weeks agoFits both my 16 inch and my 20 inch saw. Cuts straight again instead of pulling to one side, which is what told me the teeth were uneven in the first place.
4 weeks agoThe ultimate pocket-sized chainsaw sharpener — engineered for homeowners, landowners and professionals alike
Cut faster. Work smarter. Sharpen with precision.
Clean, consistent results without effort or wasted time.
A dull chain doesn't have to slow you down. RazorWolf brings every tooth back to a razor edge in just 3–5 seconds — no complicated tools, no frustration.
Fast, efficient sharpening whenever you need it: clamp it on, insert the burr, turn the handle.
Achieve professional-level sharpening without any guesswork. The built-in guide system holds the correct 30-degree angle on every tooth, so each pass is controlled and accurate.
The result is a clean, even edge across the whole chain — consistency that's almost impossible to hit freehand with a file.
No experience needed. Just clamp the tool, position it on the chain, and turn the handle. The ergonomic, stable design gives you full control.
Because the guide sets the angle for you, there is nothing to judge by eye — smooth, safe and genuinely easy, even the first time.
Made from high-quality stainless steel and durable alloy, with tungsten carbide burrs that keep their bite through heavy use.
Wear-resistant, rust-proof and reliable — a tool you can count on in the shed, in the truck, and in wet weather.
Keep your chain sharp at all times without paying for expensive sharpening services or constantly buying new chains.
One tool extends the life of the chain you already own, saving you both time and money with every use.
1. Clamp it on
Place the RazorWolf guide over your chainsaw bar and tighten the hand knobs to lock it in place.
2. Insert the burr
Slide the tungsten carbide burr through the guide bushing until it aligns with the chain tooth.
3. Crank to sharpen
Turn the manual handle 2–3 times to restore a flawless, razor-sharp edge instantly.
Everything included — no extra tools needed.
Waiting to sharpen your chainsaw is a recipe for trouble. A dull chain doesn't just slow you down — when the teeth can't bite into the wood, the bar is far more likely to kick back toward you.
By keeping a proper edge, you protect your equipment, save your back, and keep every cut clean, fast and safe. It takes a couple of minutes, and it's the difference between cutting wood and fighting it.
Yes — it fits most standard chainsaw chains on the market. The adjustable clamp locks in securely for a stable fit across different chain sizes.
Sharpening is incredibly fast — each tooth takes just 3–5 seconds, so a full chain is done in only a few minutes.
Absolutely. The guided system sets the correct sharpening angle for you, so anyone can get precise results — no experience required.
No — you can sharpen the chain directly on the saw. It saves time and makes the whole job far more convenient.
Not at all. It sharpens evenly and precisely, which reduces uneven wear and helps extend your chain's lifespan.
It's built from high-quality stainless steel and durable alloy with tungsten carbide burrs — resistant to wear, rust and heavy daily use.
