A switch-opener that works with most MX-compatible switches. Only $6.50 for a white plastic one, more for other materials.

I ordered one of these from shapeways about 4 years ago. It's still going strong after opening several thousand switches. I will say that in the past few months, I have issues opening some switches such as Bobas with this one. I dont know if it's worn out, but I suspect it might be. I have a backup one from primekb that I bought for $10 that does the trick when this one fails. Good products.
