A decent set of chisels is a good starting point.
There are many branded makes out there, all a personal choice, but I think most would agree that cheap is best avoided. my personal choice is, in the absence of good old sheffield steel, Swedish steel, chisels and saws.
I don't sharpen my saws now, files are too expensive and I can be doing other things! so i save my discarded saw steel for cabinet scrapes etc.
I don't even know where my saw horse is. As an aside, are there any apprentice saw doctors out there today today?
My dad, also time served, kept his India and Arkansas combi stones in a tin half filled with parafin and a squirt of oil, with a couple of "Slip stones".
I think they always "cut" so well because they were not full of the crud that can build up in the grain of the stone.
works well for me,
although I do the use wet and dry method,which can be easier on site, and sometimes resort to the belt sander!.
The answer is Technique and practice! Technique and practice builds confidence. regards Rodders
