Another vote for the Swan Morton here.
And another.
I have had one handle for thirty odd years, being a brass type material the butt end doubles as a file cleaner.
Mainly using 10a blades (the 10 blade is great for self surgery, the blade extends back to where I keep gripping it!).
A big box of blades bought from Squires will keep me busy for ages.
Blades I do not break often get demoted to use on another handle for cutting Milliput and applying both Milliput and greenstuff.
