Well I just got my SLP2 Knife through the letter box,And on first impression's it looks a Great design,although the firesteel/torch holder seems loose and wobbly on mine.
The Blade has no play in it at all,and is very sharp with a Good positive Lock-up and the Torch is bright enough to use for close up work.And I haven't tried the Ferro Rod yet,but it looks a Good Quality Rod,Also the Whistle does work and it's pretty loud.
I got mine for £25 and £4 for postage so I think your getting a Good deal at that price.
