I'm down a pair of fiskars hand pruners (fortunately it was my backup pair with the spring missing) and my loppers and shears are dulled.

But.

It's really great to watch my boys figuring out the kinesthetics of cutting things. The 4yo will get the lopper jaws onto a branch/trunk, brace one handle against his hips and use both arms to pull the other handle in to make the cut.
