    Frankly, I just use an old church key (bottle/can opener).

    I haven't used either of those, but an ordinary bottle opener works fine, and you probably already have one in your kitchen drawer.....if not, pick one up for $0.25 at the next yard sale you pass.

    Wow, both of those seem like a lot of work for a simple process.

    Re-loads and most factory loads I can open just by holding the cartridge near where the spool sticks out and pressing down on the spool with my thumb. Factory loads need more pressure but more than 50% of the time I can get them to pop.

    Stubborn factory loads get a pry with a gizmo I got once for free at a paint store. Bottle opener on one end and a miniature pry bar on the other. I guess they wanted me to paint with a beer buzz (to sell more paint maybe). But it works great on stubborn 35mm rolls.

    I never bother opening the cartridges. Just wind the film back and leave a leader out (or use an Ilford leader retriever).
    Load the reel from the cartridge and tear off at the end.

    Good advice all, thanks. I thought about the leader retriever too since it has other uses.

    For now the church key sounds good.

    Enjoy the fireworks tonight.

    With really stubborn cartridges, I hold the cartridge in my fist with the spool end sticking out, and slam it hard on the desk, floor, wall or whatever. Any hard flat surface will do. This always makes the end pop off. :smile:

    Good day all

    I have an old Nikor cassette opener I got when I got some reals on eBay, it looks like the first generation of the Kaiser. It works really well, I use to use the bottle opener, but when I got the Nikor I tried it and have never looked back it works well. I have never had a stubborn cassette!!!

    I make my own leader retrievers. Just cut a strip of thin plastic but fairly stiff plastic about 15mm wide ans about 80 mm long then stick a strip of double sided adhesive tape down the middle.
    To use remove the backing from the double sided tape and with the tape down push into the cassette while turning the spool as though winding the film into the cassette.

    The back of the leader will stick to the tape and can now be pulled out with ease.

    The thin plastic I used was black, I would not use clear as it could act as a light guide and cause fogging.
    You may be able to use thin card rather than plastic, not tried it but should work.

    The only caveat to the leader retriever method is to make sure the cassette felt is clean. You will be pulling the film back across it again and so if it has sand or grit (ever drop a cassette in the dirt... very bad scene) you run the risk of scratching some or all of the film.

    Many ways to skin this cat!

    That is true but fairly uncommon. The scratching on the exit slot is often mentioned however, the film has already passed through the slot twice in the camera and possibly once in production (not quite sure how they are loaded despite an Ilford tour last year!).

    I don't think I have ever had scratches caused this way.

    Am I the only one who just tears the can open? I put my thumbs in at the felt and pull it apart then pop one end off and the spool falls into my hand.

    Your camera is moving the film in a very precise way, pulling it out yourself can potentially crease or damage the film.

    I too just rip the cannister open with my thumb when I can't find my 1980s London flat metal key ring film opening thing.

    Wow, I got a kick out of this because I use the same tool. My darkroom is in the basement and I have a workbench on the other side of one wall. I needed an opener one day and this paint can opener/bottle opener was hanging on a peg above the workbench and was the closest one. Now when I open a paint can I have to retrieve it from the darkroom! :D

    I can open reloads by hand, and I use scissors[opened, and use the edge to pry it off] for the factory rolled.

    In the "good ol' days" before they crimped them semi-permanently I would hold the cartridge in the fingers and bang the long end of the spool on the table, popping the end off. Nowadays, I use a pair of heavy diagonal cutters, grab the rim (of end without spool extension) on one side with the cutting edges, and with a twist, roll the end cap off. (You won't reload it after that however.) Initially, the electrician-sized dikes were the first tool I stumbled across in the workshop that looked like it could work.

    If the "gizmo" is what I think it is, the "bottle opener" end is actually intended to be used to close the paint can, rather than using a hammer. :wink:

    Nope. :D It is a bottle opener. I go to a FUN paint store.

    I'd rather have a free bottle in front of me than a pre-frontal lobotomy.

    A bottle opener works fine for me. Ilford cannisters seem to open with much greater ease than kodaks.

    The paint store "bottle opener" in in fact a bottle opener. It is a hold over from days when paint pigments and aditives came in a seperate bottle. These were replaced with pigment in lead tubes then pre mixed colors well over a hundered years ago.

    And yet, this is a relatively "new" acquisition. Stamped on the opener is "China" and I think I got it no more than 10 years ago. Didn't scan the side that had the stamping.

    I still say it is to make it easier to have beer while painting (and thus sell more paint).

    Nevermind. I was thinking of a totally different tool. :smile:
