What sort of guff are you talking about?
I’m talking about the OP’s requirements:
I have decided I need a folding knife essentially for picnics (as cutting cheese and pork pies with a plastic knife is a game for fools). Don’t want to spend a fortune.
Although many of us have used a Swiss Army knife or an Opinel for an impromptu picnic, they are not the best tool for the job, and for food hygiene reasons I do not like the idea of a folding blade knife.
Since it’s for picnic use, something cheap and functional that won’t be expensive to replace if it’s lost, is a far better choice.
The OP referred to pork pies and cheese, but if you want to cut bread or tomatoes (which both often feature in many people’s picnics), then a serrated blade is the best tool for the job.
I keep a knife like the one I linked to in a bag on my bike, so that if the fancy takes me I can buy a baguette etc. while I’m out and have an impromptu picnic. It will do a far better job than an Opinel, a Swiss Army knife or a titanium framelock (whatever that is), and if it gets damaged or lost it’s cheap to replace.
OP, if you have young children, then possibly a better alternative to having a blade with a sharp point would be something like the Victorinox tomato knife. It doesn’t come with a solid plastic sheath, but you could probably make a very simple sheath for it, even if that just meant stapling a couple of long pieces of card together. If you also need a bottle opener and a corkscrew, then the Victorinox Waiter is the most compact of the standard size Swiss Army knives.
