TOLESA Oscillating Multi tool Hook Knife Blade, 5 PCS Multitool Saw Blades for Cutting Soft Materials Roofing Shingles, PVC Floor Carpet, Cardboard

Why I reached for these blades

I do a fair bit of roofing touch-ups, flooring patches, and jobsite cleanup, and I’m always looking for ways to replace repetitive knife work with a more controlled power-tool cut. The TOLESA hook knife blades promised exactly that: a way to use my oscillating tool to pull and push through soft, fibrous, and gritty materials without swapping to a utility knife every few minutes. After several weeks using this 5-pack on asphalt shingles, carpet, thin PVC sheet, and various packaging materials, I have a good sense of where these blades shine—and where a simpler hand tool still wins.

Build, design, and setup

The blades are made from heat‑treated alloy steel and arrive individually in plastic cases. The storage is more than a nicety—it keeps edges from knocking around in a toolbox and, importantly, keeps fingers out of harm’s way when fishing for a blade. Fit and finish are tidy, with a consistent edge grind and no burrs on the mounting face.

The twin-hook profile is the star here. One hook naturally favors a pull cut, the other a push cut. On an oscillating tool that translates to excellent control over cut direction without constantly repositioning the tool. Mounted on my DeWalt DCS355 and a Milwaukee M18, the universal quick‑release interface locked up tight with no play. There’s no Starlock compatibility, so if your oscillating tool is exclusively Starlock, these won’t fit.

Cutting performance

• Asphalt shingles: This is where the blades feel purpose-built. They skim through architectural shingles like a powered hook knife, with far less wrist strain. For ridge caps and valley notches, I could steer curves without fighting the granules. Push cuts were handy for trimming small tabs and cleaning factory edges; pull cuts excelled at long rips along a chalk line. The cut quality was clean, with minimal granule flake-off at moderate oscillation speeds.

• Carpet: On midweight carpet with a latex backing, the blades tracked straight and didn’t snag tufts. I liked the ability to glide the hook just under the backing and let the oscillation do the work; you avoid the “sawing with a knife” motion and get consistent edges for seaming. A straightedge or a stiff knee kicker as a guide helps keep things square.

• Thin PVC sheet and vinyl: At low to mid oscillation speeds with light pressure, the blades make neat cuts. If you crank the speed and lean on the tool, the edge can heat the plastic and cause some smearing. Keep speeds moderate, lift periodically, and you’ll get crisp lines without melting.

• Artificial turf: The hook contour is great for running along the backing without cutting too deep into the fibers. It’s easier on the hands than dragging a utility knife, especially on long rips.

• Cardboard and paperboard: This is not the intended playground. The blades will cut corrugated, but they don’t slice it clean like a sharp razor; you’ll see some tearing, especially across flutes. For templates and packaging breakdown, a standard utility blade or a multitool razor-holder attachment still does a neater job.

Speed, control, and technique

Oscillating hook blades reward a light touch. I got the best results at mid-range speeds (on the DeWalt, around 3 to 4) and let the edge do the work. On shingles and carpet, plunging just enough to engage the hook and then guiding along a line gave the cleanest results. On curves, I used the forward hook for push-cuts to keep the line visible and avoid overcutting.

A few practical tips that made a difference:
- Keep a stiff putty knife or scrap plywood as a sacrificial guide; ride the hook along it for straight, repeatable cuts.
- Clear shingle granules from the blade face every few minutes. A quick brush prevents abrasion from accelerating wear.
- For PVC, lower speed and intermittent contact reduce heat buildup and smearing.
- If you need super-precise inside corners, score with a razor and finish with the hook blade to avoid overcutting.

Durability and edge life

Abrasive materials like asphalt shingles will dull any edge quickly, and these are no exception. That said, the heat‑treated alloy steel holds up better than I expected for an oscillating knife profile. On a small roof project—ridge caps, two plumbing stacks, and a handful of precise notches—one blade handled everything and still had life left. On a larger run of gritty shingle trimming, I did notice the edge losing bite after sustained use, at which point cuts took more pressure and speed to complete.

On carpet, vinyl, and turf, edge life is noticeably longer; a single blade should carry you through a typical room’s worth of cuts. On cardboard, dulling isn’t the limiting factor—the geometry just isn’t ideal for super-clean slices.

I didn’t encounter any heat discoloration or chipping, and the blade bodies stayed flat under normal use. It’s worth wiping them down after dusty work; granules embedded near the edge will shorten life.

Ergonomics and safety

Compared to a roofing knife with disposable hook blades, using an oscillating tool with these hooks reduces wrist torque and repetitive strain, especially on long cuts. The hooks also keep the blade tracking in material rather than skating over the surface, which adds control around obstacles.

They’re still sharp, and the hooks are, by design, eager to catch material. The individual plastic cases are a smart inclusion, both for organization and for keeping edges covered in a crowded tool bag. Gloves and eye protection are non-negotiable on shingles; granules go everywhere.

Compatibility and setup notes

The universal interface dropped into both my DeWalt and Milwaukee oscillating tools without drama. Quick-release lugs lined up and held firm. If you’re using a Dremel with a universal adapter or other open-standard multitools from Makita or Ryobi, you should be fine. Just remember: no Starlock.

The blades are compact enough that they don’t limit visibility. I liked the slightly offset profile—it lets you work flat to a surface without the body of the tool scraping.

Value and who they’re for

You’re paying more per edge than a box of utility hook blades. For a full-time roofer who churns through hundreds of feet of cuts, traditional hook blades remain more economical. However, for a homeowner tackling a reroof, a remodeler making frequent carpet and vinyl cuts, or anyone who already reaches for an oscillating tool to save effort, the convenience and control of these hook blades justify the spend. The five-pack hits a nice balance: enough blades to carry a project, not so many that they sit unused.

If you need to do precise shingle notch work, trim ridge caps, cut around pipe boots, or make controlled straight cuts through carpet and thin PVC, these blades outperform ad‑hoc knife solutions in speed and accuracy. If your day is mostly cardboard and template work, stick to a dedicated razor.

Where they excel and where they don’t

Shine:
- Asphalt shingles: fast, clean notches and rips with less fatigue
- Carpet: controlled cuts under backing with neat edges
- Thin PVC and turf: good control at moderate speeds
- General ergonomics: reduced wrist strain compared with hand knives
- Storage and organization: individual cases are genuinely useful

Limitations:
- Not for Starlock tools
- Cardboard and paperboard cuts can be ragged
- Edge life varies; shingles will dull the blade sooner than softer materials
- Per-blade cost is higher than disposable roofing hook blades

Recommendation

I recommend the TOLESA hook knife blades for anyone who already relies on an oscillating multitool and wants a faster, more controlled way to cut shingles, carpet, thin PVC, and turf. They turn tasks that usually involve repeated knife strokes into steady, guided cuts, and the dual-hook design adds versatility you can feel immediately. The edge life is good for the intended materials, the fit on common quick‑release tools is solid, and the individual storage cases show thoughtful packaging.

If you’re a professional roofer driving long, gritty cuts every day, the cost advantage still leans toward bulk disposable hook blades. But for DIY roofing, remodelers, flooring installers, and general contractors looking to reduce fatigue and improve cut consistency, these blades earn their spot in the kit.
