I recently found 5 of grandpas old hammers dating back to the 1930s. The heads are in good shape, just a little dirty but minimal mushrooming. The handles themselves are in decent shape too, likely will strip the poly that’s on them, sand lightly up to 250 grit, and then use some wipe on poly. My main question is that there is some cracking/ gaps where the handles meet the head.... can I salvage these by putting in some new wedges to fill the gaps and use BLO to rejuvenate the woods? The handles have sentimental value so I’d like to keep them if possible. Thanks!
