When only the best will do.
Great quality and fun to work with. Easy to finish.
Cobalt chrome offers a bright finish with a smooth feel, it's a favorite! We appreciate you taking the time to leave a review, Randy. Enjoy creating! ~Sarah
Been using these blanks for quite a while now and they always come great! Cobalt has become my favorite material to work with.
It's really good, don't get me wrong. But it's also REALLY soft! I used to disarm bombs for a living, so I'm not some ham fisted Neanderthal, but I damaged it with sandpaper.
The material is phenomenal. They material is reasonably hard, so sanding is fairly stress free, and the bright white gleam looks a lot like silver. Absolutely perfect for wedding bands! (My fiancé's band is one of these, while I'm deciding between this and the tungsten..)
One big warning though: Be very careful during sanding if you want to keep the chamfer. Unlike the tungsten blanks, it's very, very easy to round over the edges during sanding. (In fact, my original review accused PAS of shipping the wrong shape of blank. Fortunately, they were cool enough to reach out to me and help me fix my technique!) If you like the rounded look, this might even be considered a feature. But if you like the chamfer, take care to sand with a firm, flat board instead of by hand. Attached is a before and after photo, so you can see what I mean.
Thanks for sharing pictures of your work and the helpful tips, James! We are always here to help our customers. Glad everything worked out for you. Keep up the creative work! ~Sarah
