(pencil lines and laser guides will suddenly look fat and
crude).

I'm always game for a new toy, but other than a rotating laser level to
install a counter, cabinets or wainscoting, I have found lasers on mitre
saws a complete waste of time. The lighter the colour of the wood, the
fatter the line. Useless.
I always have a proper Staedtler pencil sharpener in my pocket. I use 2H
pencils to mark my line and I get good results. I only go up and down
that ladder 2 or 3 times, as opposed to the usual 6 or 7.

When the weather cools off, I sometimes use a mechanical pencil as I
then have a pocket for it. In summer, the lighter wooden pencil lives on
my ear.
So much so, that when I'm on the phone, and somebody wants to leave me a
number, I reach for my ear...even though there may not be a pencil
there...much to the entertainment of my daughter.
