Knipex are real quality tools. I own several set of their pliers but not the round nose-Yet anyways.
The pair I use right now and I find work very well is made by Beadalon, I was worried as these are made for jewelry. Well I was surprised at the quality and function. I got the comfort grips(and regular but comfort grip is much better) from Michaels Arts and crafts. They sell for $20 but with my 50% coupon I ended up paying a lttle under $10. Michaels has an other pair that might sell for a bit more with black handles and they look better but are not. The Beadalon are the best they or AC moore has. Trick on getting coupon is to buy a very small item, for around a couple bucks. W/ receipt you will about 90% of the time get a coupon for the following week for 40% or 50% off.
This is also a great way to buy an airbrush, they usually have them priced about 10 to 20% more than online places but with coupon you end up saving. Call around as some of them also have Iwata airbrushes in stock, but be careful and know your prices as I have seen a couple of Iwatas way overpriced. They still make money as these two companies have a large markup margin. Thing is you can't use coupon for on sale items or combine coupons sorry for getting off topic there
