You live and learn, I had found some threads "out there" suggesting to use it for de-nibbing. Wish I had read the reviews before buying, almost all say the tool is junk!
The internet is full of experts i'm afraid, most have only read stuff never actually done it !!!, The run razor is for taking out runs which i've found it does very well to be honest or you can use a blade with a turn of tape each end.
Are those Festool thingys some thing like 40 odd quid !!!
Yes, I paid £44 inc shipping for it. Its a lot for what it is but given I plan to do a fair bit of painting on two cars I figure I will need it quite a lot.
