My grooming instructor told us not to invest in expensive shears that cost hundreds of dollars...bc once you drop it, it's never the same. I personally have a couple favs. Monk is very nice if you want to shell out $75+. I have the Monk Blue 7.5" curved which I only used a couple of x's on special clients. Mostly standard poodles. Have a box of bandages near by, it's VERY sharp!

I used this the most on my mobile grooming days. I have the 7 1/2". I think for toy-small breeds, 6 1/2" is perfect & 7 1/2" is good. Probably comes down to personal preference too. I also have the Master Grooming Tools 5200 Series Thinning Shears.

@ home, I use Fromm shears. Momo is a wiggle worm & tries to attack any grooming tool, so I put the kiss-e collar on him. I like that it's inexpensive, sharp & the handle is comfy plastic, easy to grip onto. I can drop it & not have a heart attack loll. It got pretty good reviews on amazon:
