Overview
Diablo DOU125KNFE Oscillating Hook Knife Blade is a universal-fit oscillating multi-tool accessory built for fast cutting in carpet, cardboard, and asphalt shingles. This is an oscillating hook knife blade designed for soft multi-material cutting and removal work. Model Number: DOU125KNFE. If you need a blade that can pull through flexible material without the wandering you sometimes get from a straight edge, this is the right style of accessory.
The big selling point here is the hook design. Instead of relying on a flat plunge blade for jobs it was not really shaped to do, this blade uses an ultra-sharp hooked cutting edge to make fast, clean passes in sheet material and flooring-related materials. The 1-1/4 inch cutting width gives you enough edge to cover material efficiently while still staying manageable when you are working close to corners, edges, or transitions.
Diablo builds this blade with a high carbon steel body, which makes sense for the materials it is meant to handle. For carpet removal, cardboard breakdown, and asphalt shingle cutting, the goal is a sharp edge with controlled slicing action rather than brute-force demolition. The blade body design also helps with access in hard-to-reach areas, which is useful when you are trying to start or continue a cut where space is limited.
On the job, compatibility is a big deal, and Diablo keeps this simple. The universal interface is designed to fit most oscillating multi-tools without needing an adapter, so it is a practical choice if your truck or shop has tools from different brands. The provided compatibility info specifically calls out performance with many popular cordless and corded oscillating multi-tools, but it is important to know this blade is not compatible with Starlock tools.
This accessory is a good fit for flooring installers, roofers, remodelers, maintenance crews, and serious DIY users who already rely on an oscillating multi-tool for detail work. It is especially useful when the job calls for controlled cuts in flexible material where a straight oscillating blade can be slower or less predictable. For the right task, the hook profile is not a gimmick. It is the reason to buy this blade.
Diablo DOU125KNFE Oscillating Hook Knife Blade for Tight Material Cuts
This blade is made for the kind of cutting where a standard straight oscillating blade can feel clumsy. The hooked edge helps you catch, pull, and control the cut through soft materials without needing a larger utility knife or hand cutter.
- High carbon steel body for durable cutting in carpet, cardboard, and asphalt shingles
- 1-1/4 in. blade width balances control with useful cutting coverage
- Universal fit interface works with most non-Starlock oscillating multi-tools

Pro Tip
When you are cutting carpet or shingles, start from a loose edge and let the hook pull the material into the cut instead of forcing the blade straight down. That gives you better control and helps the hook profile do the work it was designed for.
