Marking knife
So this is my first attempt at making a marking knife. I used an old kitchen knife for the blade, cut to rough dimention with an angle grinder. final size and initial bevels were done with a bench grinder (i now know i want a water wheel grinder).
The handle was made from blue gum. Initial cuts on the band saw with rasp and files to round and finish shaping. Then sanded up to 600grit. I used organ oil as a finish as its all i currently have.

Opinions or ideas of what i can do differently next time are very welcome.
Next shop tool is going to be an awl made from an old drill bit and again a blue gum handle (blue gum is the only timber ive currently got lol).

That looks like it has come up pretty well especially all being made by hand and thinking your own way through it. The only thing I can see that might improve the design is the blade could be a bit longer as it might restrict its use for getting into tighter places. For normal use it will be fine. Keep up the good work.

Good work. When I can, a marking knife is cleaner than a pencil.
I'd want to try a handle, maybe an octagon.
That way, I'd have a better mental concept of the exact orientation of the bevel.
Many of my PacNW style wood carving crooked knives have essentially square handles relative to the edge.
Nothing to wobble left of right.

Good effort. Sydney Blue Gum is one of the special timbers and I rather like organ oil despite the fact I am using Boiled Linseed Oil at the moment as that is what I have a large quantity of. If the keeper of the kitchen starts to notice a significant reduction in knife selection consider old saw plates as another good source of suitable steel.

Hi Hailey
It is an interesting design. It's special make something that is your idea and design, and then use it.
I've began making marking knives and awls nearly 2 decades ago. The last design, plus build details, for a dovetail knife and scratch awl is on my website: A Knife for Marking Dovetails by Derek Cohen
These are now made and sold by Chris Vesper.
My design for a birdcage awl is here: http://www.inthewoodshop.com/ShopMad...rdcageAwl.html
