Why spend so much,,, best knife for gutting rabbits,, is a craft knife,,with the snap off blades,,, you can pick them up for as little as £1,,, or for slightly better quality,, a few quid from b and a,,,or a stanly type knife they also work very well.
There are some types of stanlys that operate like a lock knife.
If you prefer a proper knife,,, frosts mora clipper £10 approx on line,,, or an opinal for around the same price,,, the opinal is a lock knife,, where as the clipper is a fixed blade
