A wood block (walnut, maple, cherry - I use nara) one inch thick 2.5 inch wide by 5 inch lone- with a 30 degree cut one inch in from the end. It holds the saw tip well, adds acoustic resonance - and most inportantly is easy on the hand since flexing the wrist has leverage.
The "Swedish Steel" explains why grandfather's clear purple plactic handle works so well.
