5 Minute Layout Knife!

Ever wonder what to do with those “Dull” razor blade knives that you “Break-Off” and throw away? All sorts of handy little scrapers, marking knives, mini-chisels etc. can be made from this great little piece of hardened steel.

Here is an example of what I did with the last piece in the knife.

Next simply mark out the desired shape of your tool with a sharpie, we will do a simple marking or layout knife

Next we will cut this shape out with a little cut-off wheel in a dremel tool

A quick rounding off of the sharp corners on the disc sander give us this! I have tons of these laying around my bench, a quick swipe on your strop with a little compound on it and its back to razor sharp again. I use these “As-Is” many time but a little slit in a dowel, a drop of CA glue and a quick sleeve of electrical heat shrink give a tool with more reach and versatility. Here is how I “Finished This one off”.



You can make little angle chisels, scrapers that work great for glue removal, marking knives, let your imagination and sharpie guide you! Literally less than 5 minutes from start to finish.

Enjoy!

Looks like a lot more fun than buying one.

Great job. I never throw away old blades of any kind ;-)

Very creative, there’s something enjoyable about making your own tool and using it.

Good idea, easy and fast, and then it’s easy to replace the blade.
Is it possible to shapen these blades?

nice.

just one thing to consider – this blade is double beveled leaving the cutting edge centered to the blade thickness, which might be limiting when trying to mark a line against/flush another piece (joinery etc). in which cases, a single bevel edge works better.

still – nice reuse of disposables, I’m always in favor of that.

Good point PurpLev, when you are at the belt sander its quite easy to simply grind off the factory edge and only bevel one side or the other, I have two like this, one with a RH bevel and the other with a LH bevel for tight spots its nice to have a “Dedicated’ blade to mark with. BTW, since I started using machinist squares and marking knives instead of woodworking squares and pencils the level of accuracy in my work has improved greatly. Takes a little getting used to the “Change” in procedure but once you get the hang of it a pencil line looks huge and sloppy in comparison.

Cool, I can use the old blades from a utility knife too. I keep and old plastic container with a slot in the lid to drop the used ones into. Hate to throw them unprotected into any trash container. This is a great idea, thanks for posting. BTKS

That’s very cool to make an improvement for the sake of accuracy! We all should do our best to take the time & steps to make our work better. The big plus is that you have a sweet lil item that no one (until now ) has. I sharpen my utility blades with a diamond hone in less time than replacing it. Thanks for sharing a great idea!
