Buy some epoxy resin from your local chandlers. Something like this:

Click

Mix the epoxy with the hardner in the ratio according to the instructions. Be very precise with your amounts or it won't "go off". The best way to do this is with syringes.

Mix into this some microfibres. Something like this:

Click

Mix in small amounts of microfibres until it is about the consistencty of toothpaste.

Then use the mixture like glue to stick the two bits together.

Use sandpaper to neaten it up.

I did the same thing to my Laser cb, I got told that what you can also do is carefully drill into both sections so you can fit a small metal dowel into both bits so it has more to grip to. My repair that I did has still survived many years later.

If you lose the corner you can do the following.  Drill a pilot hole and insert a screw partly into the main board.  Cut off the head and build up the corner to the original shape, with car body filler.  Sandpaper and paint.  The screw reinforces the corner so that it is less likley to break off again.

yes the screw method does make it less likely to break off but it doesnt mean it wont. when i snapped the corner off at stokes bay in the winter (dry capsize was a little energetic and my left foot was a little too far back) i was a little suprised to find i had two self tappers sticking out the bottom of the obard and as i fell off it my drysuit caught and the left leg filled up with water and i found later i had a lovely deep cut in my shin.  when i got home i took some sand paper to it and just filed the back to a smother shape. TBH you will hardly notice any performance difference with just a tiny nick out the back like that.

600 732, will call it Sticks and Stones when i get round to it.

I'm suprised you haven't bled to death by now, I'd get down the hospital ASAP. Put the end of your thumb I can see in the picture inside tuperware box on top of a bag of frozen peas that should keep it fresh until the doctors can sew it back on!

I may be better to try and make a 'biscuit cut' as you won't have much board for a screw. You can use small nails but this has been unsatifactory for me.

You'll need a small rotary blade.

Fair the tip back to square. Cut the slot with the rotary blade. Stick in the plate ( either a bit of laminate glass or metal plate ). Let that go off. Sand back the 90 degree edge you have stuck the plate into so there is more contact area for the filler. You can even dill some holes in the plate for a better mechanical key fi you want. And then fill and fair. Finish with some spray paint if yoy feel like it.

I've done something similar but using a stainless bike spoke (15p from a decent bike shop) bent into a u shape, epoxied into two holes drilled into the board and then packed out to shape with filler.  Worked a treat and no risk of exposed sharp metal if the repair fails.
