The Spiker is the first silent weapon you stumble upon on Blackreef, which allows for a stealthy playthrough. Had heaps of fun with this one.

It uses a gas reservoir to propel heavy duty nails. It was super fun figuring out the 3D shape so it's satisfactory in both while viewed in 3D but most especially in First Person.

Even on late games it remains relevant as a weapon of choice since some of it's perks transform it into a very useful ally.
