The question that I'd ask in respect of this product (if it's still around) is - who amongst golfers does not have a bag load of pencils from Ikea. And as we know these pencils do not take kindly to sharpening. So we trouser a handful every time we visit Of course I don't but my Mrs does for me
That said I do carry a pencil sharpener as it is good for tidying up snapped long wooden tees I find to make nice short ones
