There is absolutely no support for their flimsy blade lock design, the supplier didn't even reply to my email asking if there was a guarantee. So I tried MulWark after it broke but both brands have a blade lock which is difficult to engage during use and quickly fades to the point of being useless IF you don't remember not to draw the blade, when it's on. Also, the block is too fragile, the shortest case with a locked blade ruining all of its comfortable digital measurement accuracy. After MulWark broke I found the much more durable TACKLIFE MDT01 which is an auto lock meaning you just press the button to retract the blade - much more convenient and did I mention the TACKLIFE MDT01 is more durable? You are on a construction site - accidents happen - why do you need weak tools?
