>>6871095>>6871164I own both, Funtec chisels are good but I would not call them an alternative to BMC, more like an addition.
>the quality and durability of the tipNot an issue.
>how long it will lastIndefinitely if used as intended.
>sharpeningAs others already pointed out, resharpening of carbide chisels is not practical unless you already have the equipment and the skills.
The only real issue with Funtec is that they use the standard 2.35mm shank, so their width is limited by that number.
Personally I found 2.5 and 3mm BMC chisels to be the most useful for actually chiseling out material (as opposed to scribing).
