"If people want to make it heavier, let them do it themselves, the tube is hollow, so the option is there. Personally the lighter something is the less tiring it is to use
You don't want to start getting bogged down with this 'weight problem' and end up with added costs and production delays
that's my 2 cents "
Do the world a favour and listen to this advice! I could go off an a whole rant about poor products bought by the masses pushing the corporate beast forward producing ever more INFERIOR products and the "lowest common denominator" just eating it up...but I don't want to be a total jerk. Suffice it to say, weighted mice and weighted sculpting tools are NOT a good thing. Never ever. Period. It's not like a mallet or a turning chisel where the extra weight serves a purpose, all it would do is force people to fatigue sooner. Sure, you might "think" you need a few extra grams weight on the left side of your new mouse, and your choices are either weight it down OR leave it light as it is and play with it for all of a few hours and get used to it! Live the rest of your life with a lighter mouse...game, work, play, surf for twice as long without feeling the slightest hint of muscle fatigue and you can thank me for enriching the rest of your ENTIRE "mousing" life. I mean seriously...get a corded mouse while you're at it...that'll cut half the weight out of your mouse alone...try to find a corded mouse though...thanks again to the lowest common denominators.
/breath, just breath...noone is forcing me to buy a Wii after all.
Ok, so aside from that, I think the $5-$15 US per tool is a reasonable range. Although, my preference would be to have only one head per. With shapers they only have one, because, I assume, the end is not steel. So, with teflon I'd be worried about damaging the head. Even with a stainless steel head it gets nicked and scratched and the tips that are pointy get bent and deformed when I store them upright in a can/paintbrush holder/coffee cup etc.
And about the friction fit, make sure to test it after a great deal of use...real use, over real time. Because once some pressure is applied, once some temperature fluctuations occur, I'd worry the previously thick and frictiony (it's a word!) head would be worn down and start falling out. Tap and die sets are not horribly expensive and would thread aluminum and teflon fairly easy, I'd think (check into that though, before you buy). Not sure how well a teflon screw would hold though? Hrm...how to stick to the unstickable? Need to find out how they get it on those frying pans.
