Ii use to own a Canon inkjet printer and with the refill kits came a drill with a small handle to drill into the cartridge. I've repurposed these to cut tracks- just the right size.

A chap at work has been using some of the old brown stuff to cobble together 'an idea'. No idea where he found it (WEEE skip?) but the language!

I've never heard the like

Mr B's would be the preferred choice, that and the stuff which just has pads, you then have to join the pads with tinned copper wire (et al). May suit some applications carrying a bit more oooomph.

If I'm honest I rarely actually use the stripboard. Most of the ideas start on a solderless board if they are low frequency and end up on a custom PCB now they are so cheap. Anything which requires high frequency, high voltage or high current goes dead bug on plain FR4.

I'm still a fan of stripboard: as well as the traditional Veroboard-type with copper strips all the way across, in times-past I built quite a few logic-circuits using TTL and a kind of FR4 board that had sets of 16-pin DIL outlines with the 'tracks' from each pin on each chip extending outwards for 3 or 4 holes. There was a kind of turret-tag that could be pushed into the holes, soldered on the underside, and then the bit that stuck through could take 4 or 5 wire-wraps.
It also had dedicated longitudinal power/ground rails. Even better there was a special kind of ceramic decoupling-capacitor presented as a flat strip with upstanding 'legs' at the same 16-pin DIL power-pin spacing - these were great because they could be fitted _underneath_ the DIL chips before you soldered the chips in place, providing decoupling directly at the power/ground pins.

I built a number of TTL/RS232/ECL interfaces for things like a 9-track 6250BPI high-speed tape-drive to a PDP11 using this sort of approach.

Hi Kevin, the blue handle is familiar but must confess I've never seen that type of tip.
I do have the yellow and orange ones (different sizes) that can be used to insert Vero pins into the holes.

My spot-face cutter was like Kevin's, but without the spike.

That's the later one I mentioned. The tip of the earlier type was more like a short straight fluted drill bit. The earlier one looked the part better but worked no better and probably cost a few pence more to manufacture.

Looked more like pic attached

That's the one I have. A lot less harsher on the hand to use than a drill bit.
