Made myself a stick mine with barbed wire (similar to a POMZ), claymore and "danert bomb" (reel of barbed wire stuffed full of about a dozen sticks of plastic - roughly 10 lbs) back on my initial explosives course.
Oh what fun!
But any fool can make a big bang. I prefer precision charges - cutting your name into sheet steel for example. Too little and you barely knock the rust off, too much and, well, I think you can imagine.
