bit expensive if your only going to do a couple though

or this, make your own cutter:

the way I cut glass is brute, but generally effective (especially if u have a few stubbies and bottles to spare)

a cheap glass cutter like this is used to score the glass where you want the cut

the way i do it is lay the bottle down on the window ledge, with the base against the wall, hold the cutter where you want to cut and spin the bottle, making sure it never leaves the wall or ledge.

then boil the kettle.
next put some gloves on just in case!!

now in the sink poor the boiling water of the glass for a couple of seconds, then run it under the tap for a couple of second . dont use all cold water, probably about 25 degrees or so- never measured just not all cold water. then poor boiling water over the cut again, then tap water. this repetition will stress the glass where it is weakest, ie where you have scored it. keep repeating and then 5th or so time the end you are not holding will fall.

once its cut if its nice and smooth i give a smile, if not i give it a light sand.

The gloves are just in case the glass shatters while you are holding it. I have never had it happen to me before, but one could assume if the glass was defective and weaker somewhere else then it could break. and its far far easier to wear gloves then to have a tendon sutured.

this way is far better then my first way :icon-redface: , soak string in spirits, tie around the bottle, set it on fire then drop it in an ice bath- it very rarely resulted in a nice cut.

Just use a dremel or angle grinder with a thin cutoff disk. Always wear eye and hand protection. Some thin wine bottles make great test tubes once the neck is removed.
