I dont think the long version can be bought in the UK.
They are classed as a restricted item.
From what i remember they are only supplied to the emergency services etc.
If you want a bullet proof crowbar try and get a lorry tyre iron.
I looked into buying a robust crowbar like the fire brigade use and all of them are restricted items that are only for sale once your company has been vetted.
These restriction seem to go across the board with all manufactures and suppliers both in the UK and the USA.
Iv just done a search on ebay and found one

Its being sold in germany.
Plus its £100 more than a standard Fubar.
