When I was repairing my bathroom waste system, (another thread), I dropped my grandfathers little stainless steel double bladed penknife down the cavity which encloses the 110m vertical waste pipe. There is no way to recover it, so I thought I would buy a replacement. Easier said than done, does anyone know a source of these knives?

If you mean one of those simple flat handled small knives with a blade at each end then it triggeres a memory of 'where the heck did I lose mine years ago?'
Nothong that simple appears available new now although a search of twin blade pocket knives comes up with bulkier versions usually with 2 blades at the one end.
This Link has a few similar secondhand ones to my memory but not so cheap now:

Any chance that the original had some magnetic attraction? Worth trying fishing with a small neodinium?

The current crop of new S/S pocket knives don't hold an edge well in my experience.

Try an Antiques shop they used to be called fruit knives and there are still many around if you don’t mind secondhand. Dave W

I have seen them, but I can't recall how recently, in pipe and tobacco shops.

I have been looking for a "DROVER" pocket knife since my son lost it 15 years ago. Its been a source of friendly banter in the family since then.

You Won't do better than Heinnie Heinnie Heynes although personally I always buy a locking knife despite the uk legal carry laws I have had a non locker fold on me and too dangerous for me.

UK friendly

You can get some quite stiff non lockers Boker do some for instance, prices from pennies to sky is the limit.

Antique fruit knives may have silver blades, which may be too soft for anything except cutting fruit. (Carbon steel blades were not resistant to the acid in fruits and stainless was not yet invented.)

I don't think I would have any chance of fishing for it but the link to Heinnie Heynes has knives in all price ranges, and I have bookmarked them for further study. The lost knife was over 100 years old, my grandfather gave it to my mother before I was born.

Might the stainless knife nonetheless be magnetic and could it be fished out with a magnet on a string?

Victorinox used to do a knife like the one you describe ie not a "swami".

Unfortunately, there are some nails projecting on the inside which put paid to the magnet on a string approach, the knife is indeed magnetic.

I buy the same model Smith & Wesson Extreme Ops knives every so often. I have had quite a few over the years & I buy them from a shop in Ostend. They do a model with a blade just under 4 inches & I have a couple of others with a much smaller blade. I use them for work-moorings, rigging, plus on my boat etc.. I find the steel very good. Cost ( in Ostend) is circa 35 euros. but last one purchased was in 2019

I would recommend them as a single bladed "working" item. I expect that they are available online The handle is aluminium with holes in it & they can be silver or lightly blued colour. very easy to open with the thumb, locking blade, Push button or a lever lock.

I know all about the legality, but if I am on my launch trying to lift a mooring & cut something free in choppy weather trying to open a knife, I cannot fuss around.

Smith Wesson £8.95 agree about one handed opening without fuss, I also use a knife every day at work for rope nylon straps, opening boxes, needs to be quick to use and fuss free.

Depends how much working room you have and how much effort you wish to employ but some semi-rigid tube to sheathe the magnet past nails with perhaps a thin plastic rod down the tube to prod magnet past any nails...?

Also a question of how far down we're talking about - a foot or two and one of those cheap flexible graspers may be worth a go...
You can also get tiny spy cameras cheaply to try and visualise the task...

It’ll most likely be at the bottom. Make an entry there - avoiding anything magnetic above. A small hole and an endoscope might well enable you to locate it. Replacements will not be the same.

I have a folding 'Stanley-type' knife in each of my toolboxes/bags **LINK**

Not stylish or beautifully made, but very practical

UK knife law is a bit of a mine field, especially if you add in "going equipped". My "everyday carry" (EDC) is a Leatherman Charge Ti. I've carried a Leatherman for about 25 years, The Charge has two knife blades both under 4" and locking. The blades can be opened one handed. It is illegal to carry this in public in England without a good reason. As I'm no longer working as a "hands on" engineer I'd rather not have to argue the need to carry it in court. So I have cut off the locking tabs for the knife blades. The saw and file blades still lock. I tightened the pivot bolts so the blades are now effectively friction locked. I have unmodified Leathermans to carry when justified and even a TSA approved Micra that I can carry on commercial aircraft.

I bought a lovely carbon steel bladed British hand made knife a few years ago while in Scotland on holiday, it has Barlow stamped on the handle and Sheffield England on the blade I think that Barlow is the type...

I had a look at the bottom with the endoscope through the gap where the rising main goes up alongside the 110 waste. There are too many frame members on the way, the knife wasn't visible from the top either. I am just too arthritic to spend time in awkward positions.
