Having done so many different things with their tool line, Leatherman decided a few years ago to get into pocket knives. However, being Leatherman, they had to do it their own way, and look at knives with tools added, rather than their more typical method of making tools with knife blades on them. The top dog in this particular line was the now discontinued h502.
Leatherman knives are another way that they (Leatherman) have tried to secure their niche in the market today. Everyone has a pocket knife, but not everyone has one that is loaded with all kinds of Leatherman extras. My first Leatherman knife was the h502, it's a great knife that's constructed well and Leatherman was spot on with the features. The problems I have with the h502 are the size and the lack of a pocket clip. Now granted; this knife is way too big for a pocket knife and a clip would just get in the way. I still wanted all of those cool features in a package that would fit not only in my pocket but fit my needs as well.
Tool Logic is one of those companies that everyone has heard about, but no one seems to really know much about. This is a bit of a crime as ToolLogic has some excellent and innovative products, including the SLPro, Law Enforcement Model. In case you are wondering what qualifies the SLPro as a multitool, or at least worthy of being reviewed on a multitool site like this one, remember that the SLPro is more than just a one handed opening, locking tactical type knife.
Anyone who reads my reviews or ramblings on the forums knows that I have a fascination with rescue oriented tools. With all the traveling and security work I do, and have done over the years, I have witnessed more accidents than tactical knife-y situations, and I like tools that are oriented to helping victims rather than slaughtering ninjas.
My initial feelings and thoughts on the Delta knife were mixed, the knife as intended works wonderfully but I concluded that the add on features of the knife were more gimmick than something that was planned and well thought out. Some manufacturers make a product and rush it to market without fully testing the product or putting it in a real world situation to see how the tool/knife will hold up. Having carried the Delta now for six months I figure a follow-up should be in order, having since releasing the Delta model EW-O4 Sure Fire has released two new knives.
