I'm still out with the new, in with the old which is usually new to me.
Yahbut, they tell us that with all the new teknologee that the new irony is, well, I've never seen the werds superior used, just that it's "just as good". I think they were specifically citing the amount of time it takes to rust clear through.
That one is called the "falls on foot/foot hurts like hell" test. From shorter heights there's no discernable difference.
Oh! It has impact though what happens is, and this from an arm chair injineering background mind you, as it falls some of the Chiwanese cheese sheds itself. This is called the "Chiwanese Cheese Shed Factor" (CCSF). It'll lighten up by a pound or two dependent upon the height of fall/wind speed/barometric pressures and let us not forget, the all important wind chill (side of licked finger that freezes first).
In all seriousness, there's a kewl write up on the subject of Duck Tile Irony in the most recent Lee Valley Catalogette. I got mine yesterday along with the newest issue of the Dumbed Down Fine Wooddorking and a whole 10% coupon (not worth pulling on socks for) from Woodcraft.
