The Tyzack Internal Corner Trowel from Spear & Jackson produces a tight, bubble free internal corner joint and the offset blade allows the user to work right up to the ceiling or down to the floor / skirting. The 0.5mm thick spring tempered stainless steel blade gives a longer product life and resistance to rust. The trowel has a 103 degree radius which flexes to 90 degrees during use and a soft feel handle for comfortable usage, which is fixed to the blade by a chrome finished forged steel connection.
