chain breaker ?

I bought some cheap chinky chain breaker a few years ago that bent the pin first time ( even after I'd ground off the rivet ) . Chucked it in the back of the garage , but was thinking I might want to carry a good quality one with me sometimes . I always carry a few links , but got nothing to make a clean break if needed . Seen some that are mega bucks , but just want a small , lightish one , but tough enough for a 520 chain ?

They don't make a light one as such I use one that's heavy and works well but now worn, don't take it with me tho.
Gary uses a disc cutter, shocking.

Nowt wong wid a battery angle grinder. Comes in real andy like...
