Query: Expensive and useless

I loved my Rubis perforated #135 tweezers which served me well for over 15 years. When I lost them, I thought I would try the slant/point combo. These tweezers are set up so that the points come together precisely, but the leading edges of the slant do not. So the tip resembles something like this /\. There is not enough material in the tip area to grab the hair firmly (they are very sharp). Therefore, the tweezers do not grab the hair and it just slips right out. It is very frustrating. I cannot recommend them. They are for all intents and purposes useless.
