Loosening the axle nut

[tenacious]

Ok I thought I'd bury my pride and post up here because I couldn't be stuffed going out and buying another tool for the job

Last time I adjusted my chain I seem to have tightened it too tightly for my own good. Now trying to adjust it again it's bolted on solid and won't budge.

Any tips on loosening the axle bolt with just the standard tool supplied in the kit?

P.S Tried a bit of lubrication but KY doesn't seem to do the trick.
