Hand Grenades, like the Bayonet will probably never leave the battlefield. However there are severe limits in terms of possible improvements in grenades.
Improving the burst radius is counterproductive in Grenades. Decreasing the size, below a certain level, means less fragments, less effective. Now for things like Flashbangs, or Chemical Grenades then they can probably get a bit smaller. Though there is still a bottom size for chemical grenades, because you have to have a certain amount of chemicals in the grenade in order to disperse it. Other improvements will be type of explosive, but in game terms, does that really matter? Obscuration grenades, ie Smoke, might get smaller but more importantly they will have to block new observation devices. (For example hot smoke to obascure from Thermal Imagers.) That is alot of work for a one use, disposable, semi-effective weapon. About the only interesting change in the basic Fragmentation grenade might be a Frisbee shape so it can be thrown farther or around corners. (Though if you throw it wrong it can come back. )
The Bayonet is effectively about a TL2-3 weapon. (It turns a rifle into a pike.) That doesn't stop it from being used. The M1911 is a TL5 handgun but it is every bit as effective and accurate (If not more accurate) as a TL8 USP. The M2HB is a late TL5, early TL6 weapon and so far nobody has produced a better heavy machinegun. Both the M1911 and the M2HB are still in use. So even if the Hand Grenade never advances beyond TLA that doesn't mean it won't still be used.

His excellency Bhoins has a point of validity here Zparkz!
The old stuff never really goes out of style. However, as per Technology as other worthy lords and citizens have pointed out, the higher the technology, the smaller and more efficient things become--but there is a ceiling..
Typically 3 tech levels [here i steal from the T20 THB table on pages228-229]. So a TL-7 grenade would ceiling out at TL-10.
say be 90% cheaper to make each one, and 30% smaller.
+1 tech level cost reduces by -25%/ size reduced 10%
+2 tech level: cost reduced by 50%/ size reduced by 20%.
+3 tech level: cost reduced 90%/ size reduced by 30%.
You could extrapolate size reduction higher for your TU as you wish, in the path of miniaturizaions!
This is "ball parking" the topic I admit, but Traveller does a lot of that.
Now in conjunction with others posting here--grenades that use different exlosive means, or are suited for different weapons [the TL-6 smoke grenade sees replacemnt by the higher tech screening aerosol grenade vs Lase weaponry. Laser weaponry comes in at TL-9 [man-portable], so should the aerosol grenade.
Not breached beyond the smoke/ screening signalling grenades I note, are non-lethal high tech grenades.
A Decon-grenade for example to toss against an NBC shell/ grenade.
Immobilizing grenades
A netgun/ webbing grenade for entangling foes [stuff dissolves over time or maybe removed with a solvent spray--ala D20 Modern/Future.]
A deterring grenade--creates a solid ball of foam[or like blod=b shape] that encapsulates and immobilizes targets but allows them to breath--great for blocking doorways when yer running away thru a building. Again, dissolved by time or solvent.
My fav--the EMP grenades--renders everything in blast radius of non shield electronic nature slag. Inoperable.. nasty thing to go on a starship bridge or Powerplant room.. :devil:
Stunning grenades:
Psi-bombs--ala Simon Geen's Deathstalker series.
Sonic grenades--using sound waves, aka "Screamers".
Electrical shock grenades--possible.
Neural grenades--attack a target's nervous system, ad shut it down temporarily causing paralysis.
The list goes on.
In a recent book by Ben Bova "The Silent War" a corporate war over asteroid belting, the lead female character uses a flashbang grenade made of crystal--looks like a nice heavy dangly sapphire earring btw, to affect an escape from the rivals she's blundered into and intent on truth drugging her.
Flashbang grenades are TL-8. Hers disguised as jewelry might be TL-11+
