Here's a sweet new trick I just learned today from a 20 year vet and I think it's pretty cool...
"Smooth edge cut bucket from a gallon can."
If you've ever cut from a gallon can, you know that paint gets in the lip, it's messy because of the lip, the lip sucks (no pun intended).... etc.
If you're right handed, take the pointed end of your 5 in 1... place the palm of your left hand in the part of the 5 you scrape naps with, punch it into the lip of a can like you're using an old time can opener, and simply (just like those old can openers) sort of see/saw it around the lip.
Be careful when you get to the end as you can easily cut yourself when the lip comes off of the edge.
Take the blade of your 5 and smooth any jagged edges down.
Viola... Smooth and easy cut bucket in about 30 seconds.
Tried it today and it worked great!
