Hi
I was cutting some timber in work today with an old blunt hard point saw , just as i was about to throw the saw in the bin i had an eureka moment
I recycled part of the blade into a spoon knife ,,, and its really easy to do
I should stress that this was only a proof of concept . .I literally threw this together , but it works so I'll have a proper go at making one this week
Using a 4 1/2" angle grinder, I cut a 1/2 " strip of steel approx 4" long from the old saw ( sandvik 244 )
Roughly profiled it into a blade shape and again using the angle grinder i ran a bevel down the blade portion of the strip
I then cut a 4" section from an old axe shaft to use as a handle .. attached the blade to the handle by drilling three 1/8" holes to about 1 1/2" depth and then widened them to form a slot for the blade
put the "blade" into the vice and tapped the handle down onto it
with me so far ? :D
cleaned up the bevel on a wet-stone . and then stropped it . to get the curve on the blade I bent it in the vice a 1/2" section at a time ..
and this is the prototype

As i mentioned above this in only a proof of concept ,, but it works and works well

Edge retention is grand so far ... it slices through the beech pictured above very nicely . I need to experiment with a more acute bend to the blade. but it works fine and all it cost was my time

It looks like something that they find in the cells in "America's toughest prisons".
Now all you have to do Andy is to wait for another saw to become blunt :-\
As i said it was thrown together as a proof of concept ... which has now been proved
I have enough saw blade left to make 20 more ... when i get some time I'll make an aesthetically pleasing one

I hope my post didn't come across as critical. I was more referring to the 'resourcefulness' of the inmates.
Credit goes to all who have a go at making their own gear (except inmates!), something I don't have a clue about.

It reminds me of the North Western American "Crooked knives" favoured by native tribes as an all round wood working tool
Your spoon knife is much better than my attempt. It started out as a knife then turned into a fork and then the points snapped so it ended up being a long branch which i had to eat my dinner with (sorry no pics) but i will attempt a better one
What is the easiest wood to carve using a knife?
just got some 3mm o1 steel so i,ll be knocking out a couple of crook knives shortly.
you could also cut down a mora blade a bit thinner(width wise) ,bend it and quench in oil and it would still have the great grind and cutting edge. might try that too.
After a lot of testing .. they works fine on small stuff like spoons but its no good for larger items such as kuksa's or bowls , the blade flexes too much
I purchased a Svante Djarv Big Crook Knife to try a kuksa with and this was my first attempt
