Whatever kind of rider you are, it’s worth detuning the ends of your board.
The area just beyond the effective edge – where the board curves upwards from your wide points towards the tip and tail – should not be kept sharp. This is to avoid the contact points feeling twitchy when engaging a turn, which can result in you catching an edge.
Take a metal file – it doesn’t need to be a precise edging tool – and rub it at a diagonal angle to both the board and the edge.
The idea is to blunt the edge, so focus on the corner and keep filing back and forth until it is slightly beveled. You can keep adjusting the angle slightly in order to round it off smoothly.
If you’re likely to be riding a variety of terrain, stop de-tuning at the wide points – keeping the effective edge sharp.
If you’re more focused on jibbing, then de-tuning the whole of the board will mean you’re far less likely to catch an edge when boardsliding on rails, boxes and ledges.
In this case, keep rounding off the edge through its entire length, and then repeat on the other side.
Gently rub your thumb on each edge to check that they’re sufficiently blunt. If any areas are still sharp, go over them again.
That’s it – your edges are detuned.
