Twenty something years ago when I first considered straight razor shaving I purchased a razor from a beauty supply store. The case and razor says Diamond Steel Solingen Made in Germany. 5/8 round nose. It has white plastic scales. I haven't been able to find information on this razor. I'm leaning toward it being made by Dovo based on searching this form. Does anyone have any info on this razor? If so would it be a good razor to have honed and used?

Also my parents gave me a razor made by Schrade Walden. It has heavy scales like a pocket knife. Is this a razor shaped object or a razor that can be honed and used?

Thank you for any information and/or advice you can offer.
