A very short blade for the handle.
And is it a lock-knife? The metal on the handle side towards the end implies so, if so, edges into illegality, unless of course you have a good reason for carrying it.

) I only carry it around the house and land as it would be illegal in France to walk around with it. Its blade is much longer in proportion to the handle. It is not an Opinel.
We have several Opinel ones and bizarrely they are not seen as illegal, or not so much as it would take two hands to lock it!
(I know a bit more about this as I once broke up a fight, and took a blade off a kid, physically. The Head incidentally just stood by as this was going on, and once over he tried to discipline me as he "didn't like the way I took the blade off" the kid. I didn't hit him or throttle him or anything just held him until he gave it up.
So I checked and the blade was actually illegal cos of its length. But I had to research it. I nearly took it to show the plods.
At the "hearing" he eventually backed down. Especially once I proved to all present that he was not carrying out his duty of care allowing kids to run around with them, They were part of a Resistant Materials project, grouting trowels. The blade was like an Assegai. )
