looks like any "tradie" knife in tool boxes the world over. Most sharpened stiletto thin after years of damage against nails and wire.
I have the Sheffield one in the last picture. The handle is too small and great big chips broke off the edge when I used it as a pry-bar. But it gets exceptionally sharp for a $10 knife and seems to handle hammer blows fine. Mine came from Duluth Trading Co. a few years ago.I've done a variety trade jobs off and on since I was old enough to drive and haven't ever seen anyone use a knife of that type. Must be an English thing.
What do you yanks have as general utility knives?
