I have to comment on some of the observations that have been made. (Even though I see porphyre appears to have made his decision)
At the top of the list is pointing out the entire Leather man tool line is a mass produced product, and subject to day to day variances in tolerances. You are going to have a percentage that don't meet expectations for quality no matter how good the company is. The real question is how high that percentage gets, and how does the company respond to the issues when made aware of them. I've not had to communicate with Leatherman personally, but from the couple of responses people have made here, they appear to be pretty responsive.
First off for some of the comments:, unless they have changed the design a little, the scales (on mine) are not painted; they are anodized. I've been carrying mine in my fanny pack and sometimes my pocket for years, and have yet to scratch it. Anodize is usually pretty durable, but not infallible. (witness my AAA LED flashlight where after near 10 years, most of it has worn off)
Scissors: The pair on mine have been perfectly adequate, very sharp, and I have had no issues using them. In fact, they have been superior to any I've use on any Swiss army knife Ive had occasion to use. Just to be sure, I cut a number of materials just now, including paper, thread, brass shim stock, and even some corrugated cardboard. (admittedly the last was a bit tough, but it did the job.)
I will note that since scissors are a shearing tool, unless the blades are perfectly adjusted for the material at hand it is also up to he operator to use them so the blades are firmly shearing without any gap. Thin materials can often slip between the blades of any shearing device, and a little side pressure usually will prevent this from happening. This is true of everything from heavy tin snips, aviation snips, grass shears, pinking shears household scissors, and yes, even he little scissors on pocket tools. Hell, I've seen stomp shears with a little too much wear fold instead of cut thin sheet metal... That being said. if the rivet on the scissors is loose, you will have more trouble with them.
As to the saw blade having to be guided in, I can't recall a saw blade on a folding knife that didn't require some guidance, as the teeth are cut is such a way that unless a huge gap is left, any deflection will cause them to catch.
The comments on the blade/pliers/whatever being to small; no one ever claimed this tool was perfect for every job. If it's too small, you chose the wrong tool. This is a fairly small tool and not intended for heavy industrial use. Chose the right tool for the job at hand. If I am using a tool incompatible for a job, is that the tool's fault, or mine as the chooser of the tool? ( I see this is as no different than someone using a ratchet or crescent wrench for a hammer...)
As to the screwdrivers being difficult to pull out, there is a thumb nail tab for each one to get it started, and some things like that don't work well for everyone. I've had some knife blades that the nail cuts were not really properly accessible, but for me, the ones on the 4 screwdriver blades on my CS4 weren't one of them.
Bottom line is that the complaints that it is too small,, too large or the tools on it are inadequately sized for a given job is not a factor for the tool itself, but the selection of the tool for the job. All multi tools are compromises and that has to be factored by the user.
For some the CS4 is a completely adequate tool, for others something else will be better. fit the tool to your personal application. What matters here is how well it will fit for porphyre's use.
