Clog Makers Knife/Stock Knife

I love tools, and this one is pretty new to me:




It is a simple tool that multiplies the force an individual can exert, and it could be a good way to process yard waste.
The downside is the cost.
As a specialized tool for a artisan profession, they are more precious than buggy whips.
I think it would be a great forging project, something that any maker might want, and a potential homestead product.

I don't forge(yet!) but I might be able to "make" one by modifying a cheap machete.
Some machete style knives have hooks on the end that could allow them to work as is.
Morakniv makes a "wood splitting" knife that resembles draw knife, but the handles are in line with the blade.
Such a design might work as both a stock and  draw knife.
Even though this is 50-60 dollar knife, I haven't found any copy cats advertised for sale.
I suspect the handles placement can lead to accidents.

Although the knife in the first video has a  concave edge ,the blade design of  most of the stock knives seem to be mostly strait edged.
I think a convex curve could add even more cutting options, and a modified machete will offer that choice, but there is probably a reason it isn't the norm.

The Japanese have a similar tool that whose name in Japanese implies it's for chopping rice stalks. I would love something like this for chopping up Himalayan blackberries stems so we can chip and shred it without risking our lives (if you haven't met it, the thorns are seriously nasty!)

A comment in one video mentions a similar  to for cutting tobacco.
It seems that there may be a whole class of "lever blades"  that could be explored.

I did find some knives that are like the Morakniv, but much cheaper.




This design is intriguing.
It seems like some thing I could grind or forge out of a bedrail.



Here's an example of a one of those tobacco knives.


Here' s a "Chinese Medicine Slicer"


And a "Biltong Slicer"

All work on the same/similar principle as my Dad's old paper cutter. My sister says it finally died, but it had in the order of 60 years of hard use by that time!

You could easily make that with a threaded eye bolt, a piece of flat stock, and hand held power grinder,

A drill with a big bit would make some of the radius's easier to make as the cut off wheel in the grinder cut out the basic shape, and then a thicker grinding wheel used to shape up the rough cuts better.

To get the handle, welding another piece of flat stock to the handle would be super strong, or just drilling and tapping the wood to the flat bar knife part would work in a pinch.

I would make the knife part a one sided blade so that it was super sharp and you could cut right up to an edge instead of being double-bladed, but that is me. In all, a days work I would estimate. Completely doable for a homesteader on a limited budget.
