440mm slide hammer and hook set, weighing 1.3kg. - Brand: ASTRO PRODUCTS - Model Name: Slide Hammer & Hook Set - Overall Length: 440mm - Weight: 1.3kg - Included: Hook attachment x 1 Thank you for viewing. I purchased this because the hammer in my welding set for sheet metal DIY was not quite right. I didn't use it much since it was towards the end of the work, so I think it's generally clean. This is just my personal opinion, so please make your final decision based on the photos. I don't think this is suitable for those who are new to this.
