This is one of my first ever cutting tools .
its the longest flat spring out of a pack from under a 69 Ford .
I parked my bus on a piece of square tubing , put the spring in the tubing and lifted against it natural curl till Id straightened it out , no heating , no hydraulics , just lil ol me .
Then I put it in a vice and spent the best part of two days with an angle grinder and a wet rag grinding the cutting edge onto it , damp it down when it got warm , grind some , damp it down , grind it ......
I used eurothane to glue the handle on , its two bits of cupboard slat
over the years ( 7 years ) its regained some of its old curl , not much , just a bit , but it actualy works for me , so I have resisted the temptation to straighten it out again .
This knife is pretty long , I made it to suit my height when I was cutting bana grass a lot , I was sick of bending over to cut with short knives .
Its still got its original leaf spring temper , its razor sharp , has a convex grind , and isnt as heavy as you'd expect . It does a lot of damage to whatever you want to cut , I use it often in place of an axe , I made the handle big enough for a two handed grip , and when it comes to knives for chopping and digging , there isnt one I have handled yet hat beats this beast .
but she is UGLY !! Butt Ugly , still , I like it , she is my first , the first ones always is thought of fondly
