I've managed to acquire a couple of Rob Evans' knives: a Bushtool and a MK2. I like both but prefer the newer one - it's replaced the older as my favourite. Both are used regularly with my Scout troop and I really enjoy owning them. As noted above by Woodcutter, it's possible to complete most tasks with a basic Mora or Hultafors; however, the pleasure of using a knife into which I've been able to add a few requests of my own (colour, sizing, aspects of shape) adds to the overall experience of faffing about in the woods, IMHO.
Whatever sharp piece of metal you own, the key is, surely, to enjoy it and gain skills that you can pass on.
