Bloodknuckles item query

Hi Pathfinders,

I have a query / observation about the [Bloodknuckles](https://2e.aonprd.com/Equipment.aspx?ID=2559) item from Highhelm - The wraps are +1 striking wounding handwraps of mighty blows with some fun traits.

However, nowhere in the description does it mention the Bloodknuckles dealing piercing or slashing damage. So do the Bloodknuckles have a versatile P/S trait or since these are a specific magic item does it ignore the piercing or slashing damage requirement of Wounding?
