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 ?
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
