Quick answer: For homeowners and weekend cutters who want a sharp chain without a shop trip, the Sherem Saw Sharpener is worth it — as long as you know its lane. It clamps to the bar, sets the angle for you, and puts a clean working edge on chainsaw teeth in seconds, a real upgrade over freehand filing for most people. But it sharpens chains only, needs a two-hole bar, and is the same tool as $15–30 generics online. Buy it for the convenience and consistency; skip it if you want a pro-grade grind or you're happy filing by hand.

Our verdict

For homeowners and weekend cutters who want a sharp chain without a shop trip, the Sherem Saw Sharpener is worth it — as long as you know its lane. It clamps to the bar, sets the angle for you, and puts a clean working edge on chainsaw teeth in seconds, a real upgrade over freehand filing for most people. But it sharpens chains only, needs a two-hole bar, and is the same tool as $15–30 generics online. Buy it for the convenience and consistency; skip it if you want a pro-grade grind or you're happy filing by hand.

The short version

The Sherem Saw Sharpener is a pocket-sized, hand-cranked tool that clamps onto your chainsaw's guide bar and touches up each tooth with a carbide burr at a fixed 30° angle — the marketing calls it 'as easy as sharpening a pencil,' and for a quick field touch-up that's roughly fair. Clamp it on, line up the pawl, crank, advance the chain, repeat. It's aimed at homeowners, gardeners and weekend firewood cutters who want a sharp chain without hauling the saw to a shop or wrestling a round file freehand. Just set expectations: this sharpens chainsaw chains — not circular blades or hand saws — and it's a fast maintenance tool, not a replacement for a proper bench grinder.

Pros & cons

Pros

Clamps to the guide bar and sharpens without removing the chain
Fixed 30° guide keeps every tooth at a consistent angle — no freehand guesswork
Tungsten-carbide burr bites fast — a touch-up takes seconds per tooth
Small, hand-cranked and cordless, so it works in the field or the shed
Far cheaper and less fiddly than a bench grinder for quick jobs
Genuinely beginner-friendly compared with a bare round file

Cons

Chainsaw chains only — it won't sharpen circular, table or hand-saw blades despite the 'saw sharpener' name
Needs a two-hole guide bar to mount, and the burrs/stones wear out and need replacing
Near-identical generics (Libiyi, Hatmeko and others) sell for $15–30 — you're paying up for the label

How it works

Clamp to the bar

Secure the sharpener over the tip of the guide bar using the two mounting holes, so it self-aligns to the chain.

Set the tooth

Slide the pawl against the first cutter and drop the carbide burr into the guide sleeve at its fixed 30° angle.

Crank and advance

Turn the handle a few times to hone the tooth, then pull the chain forward to the next cutter and work around the loop.

Who it's for

Homeowners and gardeners who run a chainsaw a few times a season
Weekend firewood cutters who want a sharp chain without a shop trip
DIYers nervous about freehand filing with a round file
Anyone with a two-hole guide bar looking for fast field touch-ups

What does the Sherem Saw Sharpener actually sharpen — and how well?

Despite the broad 'saw sharpener' name, the Sherem is built for one job: chainsaw chains. It mounts to the guide bar and grinds each cutter with a tungsten-carbide burr held at a fixed 30° — the standard angle for most all-purpose chains. It will not sharpen a circular saw blade, a table-saw blade, a hand saw or kitchen knives, so if that's what you're after, this isn't the tool. For chainsaw teeth, though, it does the job faster and more consistently than most people manage freehand.

The 'as easy as sharpening a pencil' pitch is fair for what it is: because the jig sets the angle for you, you're just cranking and advancing rather than eyeballing a file. It's a natural fit next to a multi-tool like Kelvin in the DIY drawer — a single-purpose gadget that quietly saves you a trip. Results are a clean, working edge for bucking and limbing; it's not the mirror-perfect, gullet-deep grind a pro shop delivers, but for keeping a chain cutting between services, that's usually plenty.

Where the Sherem falls short of a real grinder

Two honest caveats. First, compatibility: the sharpener mounts through two holes in the guide bar, and not every bar has them — check yours before buying. Second, consumables: the carbide burr (and the whetstone versions) wear down and need occasional replacement, and if you lean on it too hard it can remove more metal than necessary, which shortens a chain's life over time. Light, even passes are the trick.

It also can't rescue a badly damaged or unevenly worn chain the way a bench grinder with a depth-gauge can — it touches up the cutting edge but doesn't reset rakers or true up a chain you've rocked into the dirt. Seasoned cutters on forums often still reach for a Stihl 2-in-1 file guide at the same money. Think of the Sherem as fast, good-enough maintenance between proper sharpenings, not a shop replacement.

Is the Sherem Saw Sharpener worth $45?

The catch is that the Sherem is a rebrand of a very common bar-mount sharpener sold under names like Libiyi, Hatmeko and a dozen others, frequently for $15 to $30 on Amazon. The design — orange aluminum body, three knurled rollers, carbide burr — is the same across them. At $44.99 you're paying a premium for the Sherem packaging and funnel rather than unique hardware.

So: worth it if you value ordering a known unit in one click and want a genuinely handy, beginner-friendly way to keep a chain sharp between shop visits — it pays for itself against a couple of professional sharpenings. Skip it if you're comfortable buying the identical generic for half the price, or if you already file freehand and don't mind it. And if you were hoping to sharpen anything other than a chainsaw chain, skip it outright.

Frequently asked questions

What can the Sherem actually sharpen?

Chainsaw chains, and only chainsaw chains. Despite the 'saw sharpener' name it won't do circular saw blades, table-saw blades, hand saws or knives. If you need those, this isn't the right tool.

Will it fit my chainsaw?

It mounts through two holes in the guide bar and fits most common saws in roughly the 14–20 inch range (some versions claim wider). The key requirement is a two-hole bar — check yours before you buy.

Is it as good as a professional bench grinder?

No, and it isn't meant to be. It's a fast touch-up tool that keeps a chain cutting between services. It won't reset depth gauges or repair a badly damaged chain the way a proper grinder can.

Do the sharpening bits wear out?

Yes. The carbide burr and whetstone-style heads are consumables that dull with use and need occasional replacement. Using light, even passes makes them last longer and protects the chain.

Is it really as easy as sharpening a pencil?

Close. Because the jig holds the 30° angle for you, you mostly just crank and advance the chain — much simpler than freehand filing. There's a short learning curve to get consistent, even results.

Is the Sherem the same as the cheaper sharpeners online?

Largely, yes. It's a rebrand of a widely sold bar-mount sharpener (Libiyi, Hatmeko and others) that goes for $15–30. You're paying extra for the Sherem branding, not different hardware.
