I saw these demonstrated last year at GNQS. One end is a flat two pronged fork for holding down the paper/fabric. The advantage of this is that with two points of contact, instead of just one with a cocktail stick it is not able to spin around as you work. The other one is a small cylinder (about 3/16" -1/4" diameter) that is cut off at a 20-3- degree angle and is used as the 'ironing' head for smoothing the fabric over the gluey paper. Both of the opposite ends are plain points. The appeared to be made of good quality steel. The demonstrator was show us how to make tiny dots - 1/4"(?) using the Japanese loosely woven fabric and they were near perfect. The advantage of using 2 long fine tools for the tiny details was obvious, as sometimes our fingers are too large & clumsy.
Since I am not into applique I didn't consider buying them, (besides which, I am married to an engineer - if I really want some I will ask him
) I did think them a bit steep in price, but as I said they are of a high grade looking steel, and the technique demonstrated for using them was very interesting .
