I have a aluminum chain flogger…purple chain with a leather suede handle. (Toymaker deceased). I have used it several times on some hard core masochists. The other use is putting in dry ice or the freezer, then dragging it over the body after its red and sore. Oh, and I surprise ’em with it.
There are several varieties of “Chain” floggers and just like the difference between suede/leather/rubber each style of chain will feel a bit different. Just like other floggers it is based on the size (width/diameter/thickness) of the chain, the style of chain (beaded vs. weave/link/maille) and number of falls overall weight.
My advice is to practice and see how the falls fly/spread then start very lightly and slowly.
One thing to keep in mind…flogging with metal requires a careful assessment of the bottom’s abilities and the top’s abilities in flogging. The metal in the case of mine can open someone right up if desired. Or it can be frozen and draped over them for sensation play. You can actually flog with it, it just requires precision fine-tuned control as it could easily get out of hand much more so than leather.
I enjoy chain, particularly small gauge about 12 inches long.
For fun you can heat or freeze them and it adds a whole new level of fun.
Let the weight of the flogger carry the swing. You dont need much force, unless of course you intend to cause damage but obviously youll need more intimate knowledge of your bottom to do so.
