Quest for good fine-tipped forceps - completed.
I won't bore you with the trouble I had trying to find some decent fine-tipped forceps over the years - but it has been difficult. Just letting folks know that the cheap Chinese titanium forceps I received today are simply brilliant, the best fine forceps I own (now).
The extremely fine tips align perfectly and close up right at the very end first (unlike some which touch further down such that the tips never really close). They were only £26 for 3 pairs with shipping. Some of the brand-name titanium micro-surgery forceps cost way over £100 a pair!
In summary: highly recommended if you need this kind of thing. Just search for titanium forceps on Ebay, they're quite distinctive.

For delicate things these can be great, if anyone doesn't know them:

Also look at their "featherweight" forceps. Weight is 3g .

Congratulations on your outstanding work and details given on this forum.
The best tweezers are by Dumont, easily available from any good Horological (Watchmakers) supplier.
They are also used in micro surgery, and we use Numbers 3, 4, and & 7 for making Insect microscope dissections.
Inox are the most durable , but there are many more Dumont metal alloys to choose from depending on the purpose
A quick web search gives this as an example

I do a lot of insect dissections at x25 and x50 using a dissecting scope.
For this work I use Dumont #55 straight fine forceps, biology tip.
Tip dimensions: 0.05 x 0.02 mm
Cost $46.00 (Canadian)
Anything coarser than this would be not useable for my work.

Beatsy,
If the holes in your chineese titanium foreceps have the right size compared to your fingertips, you might be able to feel your fingertips meeting through the holes just when the points of the foreceps meet. That creates a very usefull tactile feed back beeing handy when handling small living and/or fragile insects.
I have a pair of cheap plastic foreceps with another (easyly adaptable) tactile feed back: a little pin at one leg passes through a hole in the other leg. When the points of the foreceps meet I can feel the tip of the pin against my thump and adjust the pressure very precisely accordingly.

Beatsy,
Do you happen to have Dumonts No.5 or No.55 in your drawer for comparison? Otherwise your quest might not be completed yet?!
Swiss made Dumonts are kind of a high-end lab standard, presumably for some reason.
The tips of my needle-sharp #5 are the same as those of #55 that NU uses but my #5 seems to have more massive handles/shanks. Besides, #5 can be ordered in a larger variety of versions, e.g. made of various metal alloys, including titanium , and with other tip sizes.
See:

These are fine tools.
I occasionally also use my No. 5 to give friends and family members "a treat" when extracting tiny splinters from fingers etc.

Thanks for all the comments folks. Looks like Dumonts have a pretty big fan-base and they are less pricey than some brands (though I still got my 3 Chinese ones for well under the cost of one pair of Dumont tweezers).
Looks like Dumont #5's are in my near future though - you've sold me. Not 'cos I need them that much, but they are *very* fine tipped (much finer than the Chinese ones), so I'd no doubt find a use for them.
Lou - do you have a link to the scissors you were talking about? The ones I found all seem quite blunt-tipped (logical for eye surgery I guess), but I'd like some with a fine, sharp point if they're available.
Cheers

Edit: Dumont #5 titanium are £43.50 from UK suppliers and e37.50 from Germany but with pretty high delivery costs. I think I'll wait until I really need them after all.

If your forceps are not fine tipped enough you can always sharpen them with a very fine grinding stone. Just remember to keep the points together while you grind.
During my thesis on freshwater entomology I had to extract the tiny mouthparts (maxilles and mandibles) from 10 mm long mayfly nymphs and mount them on microscope slides to veryfy the identification.
They were so small that I had to sharpen my new Dumont #3 until the points looked sharp in a Leitz stereomicroscope at 30x mag.
