I believe it's Syagrus schizophylla.

I feel like I read somewhere recently that it's one of the few, or even the only Syagrus that does? My little guy in a pot doesn't yet tho.

It definitely has armed petioles. My seedlings with entire leaves haven’t yet developed them, but my one in the ground with adult pinnate fronds has developed the armed petioles. I guess they develop around when fronds start splitting. 
 

You’re right that there’s not many armed Syagrus. Here some I know of:

S schizophylla 

S coronata

S vagans

S santosii

S amicorum

 

Syagrus is a fascinating genus with a lot of variability that I think gets overlooked because of the dominance of S romanzoffiana in cultivation. Wish the other species were more commonly available. Unfortunately seed seems to have short viability for many rare species; I’ve burnt a fair bit on RPS seed for only a couple of seedlings of rare Syagrus sp. 

 

By the way, I agree on the ID of the palm in the OP being S schizophylla.

Tim syagrus romanzoffiana is very resistant to cold, this explains why it is widely cultivated even in areas where other syagrus cannot resist, I have had about ten species of syagrus, but in January 2017 we had a record cold never recorded before, all dead only the romanzoffiana alive and in excellent health

i wouldnt call them ‘spiny’ (like a Bactris, Aiphanes, etc), but they are there and not fun if they snag you

I have one in the ground, I might have to have a close look, but it certainly changes where you want to plant them as far as pathways and high traffic areas around the garden.

Yes, it's full of spines. They're like shark teeth.
