Bit of an update on this after a bit over a year or so - I did just break the Draper tool by totally abusing it trying to turn a screw it had no business turning. One of the rivets popped off so the knife wouldn't sit tight, I just removed it at and the rest of the tools still work fine but I might be looking for a replacement. Still, the good thing about cheap SAKs like this is that I was totally comfortable abusing it because it's no great loss if I do break it - and in fairness the thing has held up surprisingly well over the past year. Used the saw a lot on archaeological digs (and just gardening) when I've needed to take out a root and it does the job great for something you can just keep in your pocket. The spring for the scissors popped out at some point but that's no great loss to be honest. The screwdrivers came in useful but the Phillips one wasn't that great to be honest - I think I agree now that it's not really necessary. A smaller flathead on the edge of the can opener like on a Victorinox can turn most Phillips screws, and if you need more torque than that can give then it's not really a job for a SAK no matter what tools it has.
I never bothered to sharpen the blade and it's pretty blunt now, but it does most jobs I need it for - not going to try wood carving with it or anything. The can opener works well enough and it's pretty useful when camping, considering a lot of the cheaper soup/bean/spaghetti hoop tins don't have ring pulls. I don't think I've ever used the corkscrew, but if I was camping in France or somewhere then I can see how it might come into its own. I used the sewing "needle" once for a very specific purpose, could easily carry something better. The nail file was useful but I often just reached for a better one instead. And I could honestly take or leave the pick and tweezers. Oddly enough I didn't end up using the fish descaler
I'm not sure I'd go as far as to recommend this specific knife considering the scales popped off almost immediately and I had to glue them back on - may just be a rare fault. But at the end of the day it's done the job well and if you don't have the money for a SAK that's going to last you a lifetime you can still get a tool that's useful to carry around. Also good if you're not sure what tools you'd actually make use of day to day to get something cheap with all the bells and whistles to actually try out for yourself before you drop a bit more money on something that'll last.
I'm not sure what to get next... I'm considering getting something else fairly cheap as I graduate next year and (hopefully) might have some disposable income for the first time in my life. But at the same time I might want something I can rely on if I do end up going travelling for a bit. Sealey do some ones that look decent, assuming that logically spending more money on fewer tools would mean better quality tools. Eg;
https://www.ffx.co.uk/tools/product/Sealey-Pk34-5051747789432-Multi-Tool-8-Function < this would probably be perfect if it had a saw instead of the scissors. As it has hex bolts I'm kind of wondering if I could just swap out the saw from my draper tool...
https://www.ffx.co.uk/tools/product/Sealey-Pk10-5051747604773-Multi-Tool-10-Function < there's this which does have a saw (albeit a super short one), but I'm really not sure what I'd do with pliers and it seems a bit large/heavy to accommodate them. Similarly the Stanley leatherman clone seems to come well recommended but apparently it has non locking tools, which I've always found to be a huge pain on hex multitools for bikes
https://www.ffx.co.uk/tools/product/Gerber-31-000021-013658111721-Vise-Pocket-Multi-Tool-Black < briefly toyed with the idea of this, reckon I'd probably have more use for a can opener than pliers though and I'm not sure how effective that "serrated knife" would be on wood
