I agree with Darkness- I bought this a couple of years ago off eBay for about £40 when I changed my clutch basket.
At a claimed 450Nm it’s not very subtle but it does seem to shift stubbornly tight fixings- I certainly wouldn’t use it to do them up though so you’d still need a suitable torque wrench for reassembly.
