This, like i say is the most worthwhile pick set avaliable in the UK today containing every kind of pick and tension wrench you'll need to overcome almost all pin-tumbler and wafer locks avaliable.
The bigger Slimline sets by southord (75pc + 37pc) contain no extra picks, only duplicate picks without metal handles which are weak and uncomfortable to use.
On the other side, the smaller Slimline sets by Southord (5pc - 15PC) don't contain enough variety of picks or tension tools required for the serious lockpicker or trading locksmith.
In comparison with the other pick sets i own including HPC, GOSO and KLOM, THESE ARE BY FAR THE BEST. The grade of the steel, the overall build quality and their operational effectiveness on european locks surpass all other manufacturers avaliable.
An invaluable piece of any locksmiths toolkit!
