I am not sure the manufacturer, but I have seen these tips that have an "elliptic recess" in the tip face to hold a reservoir of solder.
I use the Metcal "bar" tip for fine pitch, because it does not involve "dragging" the tip, which can bend the IC legs and possibly delaminate the pads if too much pressure is used (especially when learning the technique). With the "bar", once it is loaded with solder, just touching it to all the pins on one side, solders them all instantly at once. Just need to use a lot of flux, like the video shows if any bridging occurs. Anything .05" pitch and larger I solder one pin at a time. Of course I use .010" solder to do it, so it's very controlled. Never use ROHS solder.
