Wow, you're serious about grooming!
Those are nice shears...my grooming instructor told us to invest in trimming shears. Plus, if you drop a shear, it's never the same, let it cut coupons.
This is what I use & love it:
PetEdge: Fromm Premier III Series Curved Ball Point Shears 6 1/2"
It's light, sharp & gets the job done. I also like the handles.
