Yes, completely safe and fine. However, i'd recommend you pick up a proper cutter from Amazon.
This one's less than $5: http://www.amazon.com/Micro-SIM-Cutter-Converter-adapters/dp/B003UEWF8I/
Or go to your carrier store and just ask for a micro sim, they are free and usually your in and out in less than 5 mins.
i haven't had to get a new sim card in years but the last time i did they charged me 35.00

I went there 2 weeks ago, just ask politely for a new micro-sim and they should just hand one over.
Atleast that's what they did for me.
