The company I'm working for at the moment supply all the tools required to do the job so theres no need for anyone to bring their own tools in. Which really is the way things should be if you're working FOR a company. However, if I was using their tools every second of the day I think I'd have to bring my own in. As one of their hand planes is actually one of those Silverline models and it isn't the best.
If you want a hand tool that is going to last go for a better recognised brand, and you will probably never have to replace it! I have got a 1950's RECORD No.6 Foreplane in my toolbox that has been passed on to me. Yes, it was rusty when I first recieved it, but after giving it some TLC it works brilliantly again. My other planes include the Stanley brand and are also great to use.
