"Looking for 30mm scale spears for 28mm minis" Topic

Hi,
firstly my apologies if I'm posting in the wrong section here; if it needs to be moved to products review/discussion that's fair enough.
I've got two armies to finish kitting out and painting this next year or two, one based in Roman era and the other on early/mid Medieval era. Kits range across GrippingBeast, Fireforge, WarlordGames and Victrix mostly, with smallest scale being Imperial Roman legionnaires from WarlordGames and largest probably being Norman infantry from Victrix. With all of them, I'm becoming saddened by the spear tips – from a distance I can't easily make them out. In this respect I'd like to depart from historical realism a little bit and give all of the spear wielders a larger spear tip, with most likely a triangle / diamond shape which again can be picked out from a few yards as a classic shape. However I'm having trouble finding them online; I can find Warhammer scale (I guess roughly 32mm scale) spears being sold which are comically oversized on my 28mm figures, but I'm not finding something in between. If anyone knew of a maker out there who offers these halfway scale tips, please let me know. I've even thought outside the box a bit and tried looking for say 54mm troops with arrows, in the hope that the arrow tips might serve such a purpose, but no luck yet.

Basic example of design that's too small:
Fireforge 5cm spears pack, thickness (of spear haft) 1.7mm

Basic example of design that's too big:
Late 90s plastic Tomb Kings spear arms

You may want to give Old Glory a try. They come with steel poles and, what appear to me as, cast oversized points. Some assembly required and best to drill out more on the mount point with a pin vise.

Piano wire and a dremel to cut and shape it

Have you also rejected the wire spears from Northstar? They are the standard for 28mm historical gaming.

Thanks Colonel, Bowser and Ran for the comments. Had a look at the offerings by Old Glory and Northstar but alas, those spearheads at the widest point look like 1.4/1.5mm, whilst I'm aiming for 3mm. Not a scale choice unique within Northstar; their 'trade weapons' muskets are oversized and perfect for my other civil war / napoleonic army.
I'll have a go with wire / rod sure, just a question of the time it'll take overall given the number of spear troops to improve. Found another option on my travels, 'spikey bits' from WaylandGames, the top half of some of those might serve as what I'm looking for. Saga continues! But thanks for input.

In case you manage to find plastic spears with over-sized tips, could it be feasible to trim those speartips with a knife until they would look good for your tastes?

Yes I think this is what effectively I'll have to do a little bit with these 'spikey bits' which are meant for 40k armies I think. I'll have to see whether they turn out looking more like a large fat jewel, or (hopefully) a deadly spearhead!
