See these common finish choices below. Note that finishing options are dependent on wood type and application, and any options and recommendations will be discussed during the project design phase.
Hardwax Oil - Moderately durable penetrating finish with beautiful grain enhancement and low-mid gloss; easily repairable; great for most low-medium duty applications
2K Hardwax Oil - harder wearing penetrating finish suitable for heavy use on tabletops; low-mid gloss; numerous tint options
Shellac/polyurethane - Very durable finish with excellent grain enhancement and a more "vintage" warm appearance, especially on black walnut; available in a variety of sheens
Polyurethane - Very durable clear finish with minimal grain enhancement; suitable for some woods, but can appear dull on others without use of a tint/stain/glaze; available in a variety of sheens
