Dear Jonas and Devonian

[NorthernRaider]

Ref your thread elsewhere, do a google for Caltrops Easy made and very effective, I've seen em made from bits of barbed wire.

[Devonian]

Thanks NR, didn't know they were called that.

If I recall correctly the IRA used to use them made from 6" nails??

[Midnitemo]

They are the land mine of ancient times, used for area denial and funneling attacking forces into kill zones...still have there uses today, floor boards with nail knocked through are a good improvisation that will slow people up in the dark or close country.

[Straight Shooter]

Yes Midnitemo....slowed me up alright....never knew they existed, or had a name for them .....thought I invented something special.....bugger!

[Jonas]

Thanks for the tip NR. Some of those things look downright nasty!
