UK Legal Karambit help

[matty78943]

ok so being a lover of (swiss army) knives in the uk it is hard to have knives but i love karambits and balisongs.

1. Balisongs are a big no-no so i have to use trainers or just no flipping
2. Karambits are not legal Or so i thought?

so i found this ^^^ what appears to be a slipjoint folder (almost put slipknot folder XD(although i do like slipknot))

so what is peoples opinions. is it going to be any good?
also if you can find any good trainer (no blade - not even dull has to be one with the holes in the "blade")
