Yes - the Kookaburra Crown I believe it was that Rob mentioned as he was shaping this in front of me, think he bashed a fair few of these out back when he was working for Kook. I've found the handles to be a good thickness, and I think he has some thicker handles in so can always do that. The H4Ls I get don't tend to have skinny handles, but then again I don't shy away from heavier weights/getting them to keep the weight down, so that could be a factor!
Got one myself a few years back during their very popular on here phase and tried a few others, all at sensible weights and they had extremely thin handles - really put me off. Been a while since I've seen much to be fair, they seem to have waned in popularity a bit around this way, so could be they've thickened them up.
