It looks like a vintage Cadet II - vintage because (I think) the current-production alox models have a sort of 'basketweave' or 'criss-cross' pattern to the scales rather than the 'all vertical' scales on this knife. Looks to be in excellent shape.
(The Cadet I, which is still in production, replaces the small knife blade with a nail file/large Philips driver combo blade. The Cadet II was discontinued in 2007 or perhaps early this year.)
