You should try to get your psychiatrist to switch you to valium. Valium has a much longer half life than klonopin and is much easier to come off of. Klonopin's half life is around 34 hours while valium's is around 100 hours. If he still won't do that and you are desperate to come off, you should start shaving tiny amounts of the pill. When I say tiny I mean 10% of the pill. I know the pills are already so small so it is a very tedious process. If that doesn't work then start dissolve it in water and calculate with doses that way. But only start with 10% at most every two weeks. So if you are taking two doses a day only start with shaving just one of those doses. I would not use a pill cutter either, because you have a lot less control of where it cuts.
You could also just ask your primary care or another doctor for help. Most GPs are quite biased against benzos so they love the thought of taking people off of them. But your absolute best option would be to switch to valium and come off that way. If you tolerate klonopin then you can probably tolerate the valium because those two are very similar. I personally hate both of those and they actually make my anxiety worse. They are much different than xanax which is still the best for severe sudden panic attacks. Klonopin doesn't really work as well to take as needed so that's why doctors tend to like it better for long term use to prevent attacks before they start. It works better once you start taking it daily and it tends to be easier to come off of than xanax, but valium is easier to come off of than klonopin.
Read a book called the Antidepressant Solution by Glenmullen. This will give you a general guide to when it's time to stop a drug and how to do it. But this is the general guidelines I discovered when researching this (too late, my psychiatrist was clueless and left me broken): the schedule for tapering off a drug is as long as it takes you to do it without suffering a horrible withdrawal. You don't say how long you've been on klonopin, but you've been on a very high dose, and you're experience so far shows it will be very hard for you to stop. So do it very very slowly. If it takes a year, it takes a year. Maybe you'll never be able to stop and feel good enough so maybe you'll stay on it, but if you want to try, again, as slowly as it takes you to do it. Don't follow any schedule arbitrarily set by a psychiatrist; follow one that suits you. Also know that, at some point, you're probably going to suffer withdrawal and will have to push through it, but what you don't want is one that lasts a long time or forever or that gives you emotional problems you didn't have before you went on the drug in the first place. So, you know that going down after two weeks was too fast for you -- you go back up to the last dose at which you felt fine, and taper off more slowly every time it gets really bad. So maybe take a month before you taper down more. You can also cut your pills to titrate down very very slowly. Your psychiatrist won't want to do this -- it takes too much time and he's got patients to make money off of. Doesn't want to spend all his time with you. You have to make it clear he works for you. You have to set the schedule, because most of what doctors know about drugs they learned from the pharmaceutical companies that made them and paid people to write the textbooks, and they lied. Take it into your own hands, you're the only you. Some do this very easily, some don't. You don't. Have patience. If it doesn't work, the worst that happens is, you stay where you are now, but with enough time, exercise, relaxation exercises, therapy and the like to help you, you should make it through. Peace.
