I would give the st 300 a 10 out of 10 based on my usage,the handles were very confortable and it was easy to loosen the nuts holding the battery cables and the battery holder.like i said it only took a couple of minutes start to finish the leatherman couldn't have been more usefull.the tech at sears was supprised how fast it went.this is a very solid tool,i have carried it everyday and have never needed anything else.very tough.
My wife and I were going into town to see a movie friday night,we stopped to get gas and her car wouldn't start,I asked her to get her battery checked out a week ago,but needless to say I was stuck at the gas station untill I could get someone to jump start the car,we headed to sears to get the battery tested and ofcourse it was dead as a doornail.sears says no problem we have a battey but there is a 2 hour wait to get it changed.So i say no problem i have a leatherman tool i will change it myself,the guy laughs and hands me the battery.By the time he comes to check on us the battery is changed and i hand him the old one,he says wow that was fast,are you interested in a job,i tell hem no thanks and he says you saved yourself $12.We made the moive on time and saved some money,thanks to my supertool 300.maybe a good tool can pay for itself.
