I like the Kershaw/Emmerson knives because they are cheap and effective. You can usually find them for about $20 and at that price you can throw them away after they earn their keep. Are they as solid or high quality as a "Real" Emmerson knife? Nope. But then again they are not $200 either. You get what you pay for.
The thing that I really like about these knives is that they are cheap enough to willingly abandon if you have to. I have taken a few of these on international trips, cruises and things like that which usually frown on knives. If it gets confiscated or I have to abandon it in an airport while traveling its not a big loss.
